How to Change Your Password on iPhone: Passcode, Apple ID Password, and Saved Passwords

At first, this sounds simple enough: you just need to find where the password is changed on an iPhone. But that is exactly where people get tripped up. On iPhone, the word “password” can mean a few completely different things. For some people, it means the passcode used to unlock the screen. For others, it means the Apple ID password. And sometimes, a person is really trying to change the password for email, banking, Instagram, or another app they use on the phone.

That is why it is so easy to land on the wrong guide. You may want to change the lock screen code, but end up reading about Apple ID. Or you may be looking for your Apple account password, while every article keeps talking only about screen lock settings. The topic sounds the same, but the actual solution depends on what you are trying to change.

Here, everything is separated clearly: one part for the iPhone passcode, one part for the Apple ID password, and one part for passwords saved for websites and apps. And if the problem is no longer about changing a password but about losing access, there is a separate section for that too.

The basic idea is simple: if you want to unlock your phone, you need to change the passcode. If you want to access Apple services, you need to change your Apple ID password. If you want to update a login for email, social media, or another service, you need to change the password for that specific account.

What exactly do you want to change on iPhone

The first thing to do is not rush into Settings, but figure out which password you actually mean. On iPhone, there are several different types of passwords, and each one does a different job.

iPhone passcode

This is the code you enter on the lock screen to unlock your phone. Even if Face ID or Touch ID is turned on, the passcode still exists. It is used for important confirmations and in situations where biometrics are not available. Most of the time, this is what people mean when they ask how to change a password on iPhone.

Apple ID password

This is the password for your Apple account. It is used for iCloud, the App Store, backups, syncing, and other Apple services. It is not the same as your lock screen passcode, even though people often mix the two up.

Password for a website or app

This could be your password for email, social media, online banking, or an online store. Your iPhone may store these details and fill them in for you, but the password itself belongs to that website or app, not to the phone. In that case, you need to update either the login settings on the service itself or the saved entry on your iPhone.

When the issue is not the password but access

Sometimes a person searches for how to change a password, but the real issue is different: the phone is already locked, the passcode is forgotten, the device is not accepting the correct code, or the screen says the iPhone is unavailable. That is no longer a normal password change. It is an access recovery situation.

So before doing anything else, it helps to understand which case you are dealing with. Once that is clear, the right solution becomes much easier to find.

How to change your iPhone passcode

If you want to change the password used to unlock your iPhone, what you actually need is the passcode. For most users, this is the main scenario. It protects the device, confirms sensitive actions, and works alongside Face ID or Touch ID.

Where to find passcode settings

To change your passcode, open:

Settings → Face ID & Passcode

or

Settings → Touch ID & Passcode

The exact name depends on your iPhone model. Newer devices usually show Face ID, while older ones show Touch ID. When you open this section, your iPhone will ask for the current passcode. Without it, you will not be able to change security settings.

How to change the passcode on iPhone with Face ID

In most cases, the steps look like this:

1. Open Settings.
2. Go to Face ID & Passcode.
3. Enter your current passcode.
4. Tap Change Passcode.
5. Confirm your old passcode again.
6. Enter your new passcode.
7. Enter it again to confirm.

After that, your iPhone will start using the new passcode. This is the code you will need whenever Face ID does not work or the phone asks for an extra confirmation.

How to change the passcode on iPhone with Touch ID

On iPhones with Touch ID, the process is almost the same:

1. Open Settings.
2. Go to Touch ID & Passcode.
3. Enter your current passcode.
4. Tap Change Passcode.
5. Enter your old passcode again.
6. Set a new passcode.
7. Confirm it one more time.

So the difference is mostly just the name of the menu. The overall logic stays the same.

How to choose a 4-digit, 6-digit, or alphanumeric passcode

A lot of people assume iPhone only gives one standard passcode format. In reality, you usually have a few options:

• 4-digit numeric code
• 6-digit numeric code
• custom numeric code
• custom alphanumeric code

A 4-digit code is faster to type, but it is also weaker. A 6-digit code gives you a better balance between convenience and security. If you want stronger protection, you can use a longer numeric code or an alphanumeric one.

For everyday use, a 6-digit passcode is usually a good middle ground. It is noticeably stronger than a short code without becoming annoying to use.

Can you turn off the passcode

In some cases, yes. But before doing that, it is worth asking whether you really want to.

Without a passcode, your iPhone becomes much less secure. Also, some important security features rely on it. If your phone contains banking apps, photos, messages, work files, or access to important accounts, keeping a passcode is the safer choice.

Why iPhone still asks for the passcode after Face ID or Touch ID

This is one of those little things that catches people off guard. Face ID is turned on, but the phone still asks for the passcode from time to time. That is normal.

Your iPhone may ask for the passcode in situations like these:

• after restarting the device
• if the phone has not been unlocked for a while
• after several failed biometric attempts
• before important security changes
• in other protected situations

So biometrics do not replace the passcode completely. They just make daily access faster and easier.

What kind of passcode is best

The worst choice is an obvious combination like 1234, 0000, 111111, or something too close to your birthday. Those are easy to guess.

A better passcode should be:

• not obvious
• not tied to your personal details
• easy enough for you to remember without writing it down somewhere risky

At the same time, a passcode that is so complicated you forget it in a few days is not a great choice either. The goal is balance. A good passcode should not be predictable, but it also should not lock you out of your own phone.

How to change your Apple ID password on iPhone

Now let’s talk about the second big scenario. If your issue is not unlocking the phone, but accessing iCloud, the App Store, backups, and other Apple services, then you need to change your Apple ID password, not your iPhone passcode.

This is where people often get confused. On the surface, it still sounds like the same “password on iPhone,” but it is actually a completely different layer of access.

When it makes sense to change your Apple ID password

People usually change it in situations like these:

• the password has not been updated in a long time
• it feels too simple
• you think someone may have accessed your account
• you cannot sign in to Apple services
• you noticed strange account activity
• you want stronger protection after losing a device

If the issue involves iCloud or Apple services, this is probably the section you need.

How to change the password through Settings

The easiest way is usually right on your iPhone:

1. Open Settings.
2. Tap your name at the top of the screen.
3. Go to the sign-in and security section.
4. Find the option to change your password.
5. Confirm your identity with your device passcode or another method.
6. Enter a new password.
7. Enter it again to confirm.

Once that is done, your Apple ID password is updated. In some cases, you may be asked to confirm sign-in again on certain devices or services.

How to change the password in a browser

If you prefer using a computer or another device, you can also update your Apple ID password in a browser. This is useful when you do not want to dig through the phone menus or you are already working from a laptop.

The basic flow is usually this:

1. Sign in to your Apple account management page.
2. Confirm your identity.
3. Open your security settings.
4. Set a new password.

Still, if your iPhone is right there and you have access to it, changing the password through Settings is usually faster.

How to change the password for a child account

If this is a child account in a Family Sharing setup, the process may be a little different. In that case, an adult managing the family settings usually needs to be involved. It is best to move carefully here so you do not accidentally create confusion with account access across the family group.

What you may need to change your Apple ID password

Your iPhone may ask for one or more of the following:

• your iPhone passcode
• access to a trusted device
• two-factor authentication confirmation
• another identity check

That is normal. Your Apple ID password controls too many important things to be changed without extra verification.

What a good new Apple ID password looks like

It is best not to reuse the same password you already use for email, social media, or other important accounts. If the same password is used everywhere, one leak can trigger a chain of problems.

A separate strong password for your Apple account is already a smart step toward better security.

How to change a saved password for a website or app on iPhone

There is another common case too: you do not need to change the screen lock passcode, and you do not need to change your Apple ID password. You just want to update the password for email, Instagram, a banking app, a shopping account, or another service you use on your iPhone.

Here, one thing matters: your iPhone can store these passwords, autofill them, and help you sign in, but the password itself belongs to the website or app, not to the phone.

Where to find saved passwords on iPhone

iPhone has a section where logins and passwords are stored. There, you can:

• view saved entries
• find a specific site or service
• edit older login details
• remove entries you no longer need
• review weak or reused passwords

This is useful when you already changed the password on the website itself, but your iPhone still has the old one saved.

How to update a saved password

The process is usually straightforward:

1. Find the service in your saved passwords list.
2. Open that entry.
3. Go into edit mode.
4. Replace the old password with the new one.
5. Save the changes.

But there is an important detail here: sometimes you are not actually changing the account password itself. You are only updating the information your iPhone stores for autofill.

When you need to change the password on the website itself

In most cases, the real password change happens inside the account settings of the website or app. After that, your iPhone will offer to save the new login details, or you can update them manually.

So if you need the password for a specific app or website, the first place to check is the security settings of that service, not your iPhone passcode menu.

What passkeys are

You may also come across passkeys. These are a newer sign-in method that is gradually replacing traditional passwords. Instead of typing a password every time, sign-in is confirmed using a secure method on the device, such as biometrics.

For everyday users, the takeaway is simple: if the issue is a password for a specific website or app, do not look for the answer in your iPhone lock code settings. It is a different path.

What to do if you forgot the password or iPhone will not accept the code

This is where the situation stops being a normal settings task and becomes stressful. If the passcode will not come back to you, the phone will not let you in, or the screen says iPhone unavailable, it is better to slow down and avoid random attempts.

The first thing to figure out is what exactly is missing: your iPhone passcode or your Apple ID password. That decides everything that comes next.

If you forgot your iPhone passcode

If the passcode is completely forgotten, the normal change menu will not help. Your iPhone asks for the current passcode first, and without it, you are dealing with recovery, not a regular passcode update.

In this situation, the worst move is entering random combinations over and over. That can quickly lead to temporary lockouts and make the whole situation worse.

If the passcode does not come back to you at all, you may end up needing to erase the iPhone and set it up again. That is exactly why backups matter. They are not just a nice extra. They are what helps when access is already gone.

If iPhone says the device is unavailable

This message usually means there have been too many incorrect attempts. At that point, it is better to stop and not keep guessing.

What usually happens next is something like this:

1. Accept that the passcode is not coming back right now.
2. Make sure you have access to your Apple account.
3. Move to device recovery.
4. Erase the iPhone if needed.
5. Restore your data from a backup, if one exists.

So the goal is no longer “maybe I will remember it on the next try.” The goal becomes getting control of the phone back without making things harder.

If you forgot your Apple ID password

This is a different problem. Your iPhone itself may still unlock normally, but you cannot sign in to iCloud, the App Store, or account settings.

In that case, what you need is Apple ID password recovery, not a passcode change. Depending on the situation, you may need:

• access to your own device
• a trusted phone number
• another identity verification step

If your iPhone is already linked to the account and you still have access to the device, recovery is usually much easier.

If you changed the passcode recently and already forgot it

This happens more often than people expect. Someone changes the passcode, and then a few hours later or the next day they are no longer sure what they set.

If that sounds familiar, try to remember the pattern behind the new code, not just the exact digits. A lot of people forget the numbers themselves but still remember the logic, such as a shifted date, a familiar number sequence, or part of the old code.

If the phone is still unlocked and you still have access, do not wait. Change it again to something you know you will remember.

What to do if iPhone will not accept the correct passcode

This is one of the most frustrating versions of the problem: you are almost sure you are entering the right code, but the phone keeps rejecting it.

Start with the simple possibilities:

• are you mixing up the old passcode and the new one
• are you entering the code from another device by mistake
• did you change the passcode very recently
• are you typing too fast
• are you getting the number order wrong

Sometimes the explanation is more ordinary than it feels in the moment. But if there have already been many failed attempts, it is safer not to keep testing possibilities.

When you may need to erase your iPhone

If the passcode is completely gone from memory and there is no normal way back in, the iPhone may need to be erased. After that, you set it up again, sign in to your Apple account, and restore your data from a backup if you have one.

The usual path looks like this:

1. Set up the iPhone again.
2. Sign in to your Apple account.
3. Restore your data from a backup.
4. Create a new passcode.

If there is no backup, some data may be lost. That is why backups are not something to leave for later. They are a practical safety net.

How to change your password more safely and avoid losing access

Changing a password does not automatically mean everything is done perfectly. It is worth checking a few things afterward so you do not create a new problem for yourself later.

What a strong password should look like

A good password should not be obvious. If it is your birthday, 123456, your name, or something easy to predict, it is not doing much for you.

A better password should not:

• repeat other important passwords
• be too simple
• include obvious personal details

The same logic applies to your passcode. The more predictable the combination, the weaker the protection.

What to check after changing your Apple ID password

After updating your password, it is worth taking a few extra minutes to make sure your account still looks right. For example:

• is your verification phone number still current
• do you still have access to your trusted devices
• are there old sessions or devices you no longer need
• are your recovery options available

It is a small check, but it often turns out to be more useful than people expect.

Why you should not use the same password everywhere

If the same password is used for email, social media, and your Apple account, one leak can put everything else at risk too. That is why important accounts should not all share the same password.

Yes, using different passwords takes more effort. But losing several accounts at once is a lot worse.

How to tell if your password may have been exposed

Signs can include strange sign-in alerts, account changes you did not make, suspicious emails, or other activity that feels off. If something looks wrong, it is usually better to change the password right away and review your security settings.

Which security settings are worth reviewing

After changing a password, it is useful to go through a short checklist:

1. Make sure you really remember the new password or passcode.
2. Check that the correct login details are saved.
3. Review your recovery methods.
4. Make sure backups are working.
5. Look over your main account security settings.

It does not take long, but these small steps can save you a lot of trouble later.

Quick answer: how to change the password on iPhone in your case

If you need the code used to unlock your phone, open Settings, go to Face ID & Passcode or Touch ID & Passcode, enter your current code, and choose the option to change it.

If you need your Apple account password, open Settings, tap your name, go to your security settings, and change the Apple ID password after confirming your identity.

If you need the password for email, social media, or another service, start in the settings of that website or app. Then update the saved password on your iPhone if the phone still has the old one stored.

And if the passcode or password is already forgotten, skip the normal change instructions and move straight to recovery.

Frequently asked questions

How do I change the password on iPhone if I mean the lock code

You need to open Settings, go to Face ID & Passcode or Touch ID & Passcode, enter your current passcode, and choose the option to change it. That is how you update the code used to unlock your iPhone.

Where do I change my Apple ID password on iPhone

Your Apple ID password is changed in your account settings, not in the passcode menu. Open Settings, tap your name, and go to the security section to update it.

What is the difference between an iPhone passcode and an Apple ID password

Your passcode is for the device itself. It unlocks the screen and confirms certain actions. Your Apple ID password is for your Apple account, including iCloud, syncing, purchases, and other account features.

How do I change a 6-digit passcode to a 4-digit one

When changing your passcode, iPhone usually lets you choose a different format through passcode options. That is where you can switch to a 4-digit code, although it is less secure.

Can I turn off the passcode on iPhone

In some cases, yes. But it is usually not the best idea. Without a passcode, the phone is less secure, and some security-related features are less useful or work differently.

What should I do if I forgot my iPhone passcode

If you cannot remember it at all, you usually cannot change it through normal settings. You will need to move into recovery, and in some cases that means erasing the device and restoring your data from a backup.

Can I change my Apple ID password without my iPhone

Yes, you can do it in a browser too. But you will still need to verify your identity. If you have access to your iPhone, doing it on the phone is usually easier.

Where can I find saved passwords on iPhone

You can find them in the part of iPhone settings where saved passwords and login details are stored. From there, you can open an entry, edit it, or remove it.

What if my iPhone will not accept the correct passcode

First, make sure you are not mixing up the old and new passcodes, typing too quickly, or using a code from another device. If there have already been many failed attempts, it is safer to stop and move to recovery.

Will erasing iPhone delete my data

Yes, erasing the device removes local data. You can restore it from a backup if one was created earlier. That is why backups matter so much.

Conclusion

The tricky part about the topic “how to change your password on iPhone” is that one phrase can point to several completely different tasks. Some people need the passcode used to unlock the phone. Others need the Apple ID password. Others just want to update the password for a specific website or app.

Once you identify which one you actually mean, everything gets much easier. For the phone itself, you change the passcode. For Apple services, you change the Apple ID password. For third-party services, you change the password for that specific account.

And if access is already gone, the most important thing is not to confuse a normal password change with account or device recovery. That distinction is usually what saves the most time, stress, and unnecessary steps.
