How to Change Your Password on Your iPhone

Whether you're updating your Apple ID password, changing your iPhone's screen passcode, or resetting credentials inside a specific app, the process varies depending on exactly which password you're trying to change. iPhone manages several distinct types of passwords, and knowing which one you're dealing with is the first step.

The Three Main Passwords on an iPhone

Most people asking this question are referring to one of three things:

• iPhone passcode — the PIN or alphanumeric code that locks your screen
• Apple ID password — the password tied to your Apple account, used for the App Store, iCloud, and Apple services
• App or website passwords — credentials stored in your iCloud Keychain or a third-party password manager

Each is changed in a completely different place.

How to Change Your iPhone Screen Passcode

Your screen passcode (the 6-digit PIN or custom code you enter to unlock your phone) is separate from everything else. Here's how to update it:

1. Open Settings
2. Tap Face ID & Passcode (or Touch ID & Passcode on older models)
3. Enter your current passcode when prompted
4. Scroll down and tap Change Passcode
5. Enter your current passcode again, then set your new one

By default, iPhone suggests a 6-digit numeric code. If you tap Passcode Options, you can choose:

• 4-digit numeric code — simpler, less secure
• Custom numeric code — longer number string
• Custom alphanumeric code — letters and numbers, strongest option

🔐 Your passcode is also tied to data encryption on your device. A stronger passcode directly improves your device's resistance to brute-force attacks if someone physically has your phone.

What If You've Forgotten Your iPhone Passcode?

If you don't remember your current passcode, you cannot change it from within Settings. You'll need to erase and restore your device using a computer with Finder (Mac) or iTunes (Windows), or through Recovery Mode. This process wipes the phone, so having a recent iCloud or local backup matters a great deal here.

How to Change Your Apple ID Password

Your Apple ID password is managed through your Apple account settings, not your iPhone's system settings — though you can initiate the change from your device.

On your iPhone:

1. Open Settings
2. Tap your name at the top (your Apple ID banner)
3. Tap Sign-In & Security
4. Tap Change Password
5. Enter your iPhone passcode when prompted, then create a new password

Apple enforces specific password requirements: minimum 8 characters, including uppercase, lowercase, and a number. You also cannot reuse recent passwords.

Alternatively, you can change your Apple ID password from any browser at appleid.apple.com — useful if you're locked out of your device or changing it from a non-Apple device.

Apple ID Password and Two-Factor Authentication

If two-factor authentication (2FA) is enabled on your account (and it should be), changing your Apple ID password will trigger a verification code sent to your trusted devices or phone number. This adds a layer of confirmation that you — not someone else — are authorizing the change.

After changing your Apple ID password, you may be signed out of iCloud on other devices and asked to sign back in with the new credentials. This is expected behavior.

How to Change Passwords Saved on Your iPhone

If you're trying to update a saved password for a website or app — stored in iCloud Keychain — your iPhone can guide you there too.

1. Open Settings
2. Tap Passwords (you'll need Face ID, Touch ID, or your passcode to access this)
3. Search for the account you want to update
4. Tap the entry, then tap Edit
5. Update the password field manually, or tap Change Password on Website to go directly to that service's password reset page

🗝️ As of recent iOS versions, Passwords has been elevated to its own dedicated app on the home screen, making this process more accessible than in earlier versions where it was buried deeper in Settings.

What About Third-Party Password Managers?

If you use 1Password, Bitwarden, Dashlane, or a similar app, your saved passwords live inside that app — not in iCloud Keychain. You'd update those credentials from within the respective app's interface. iPhone's built-in Settings won't show passwords stored externally.

Factors That Affect the Process

Several variables change how straightforward any of these steps are in practice:

Users on older iOS versions (pre-iOS 14 or 15) will find some of these menus in slightly different locations — for example, Passwords may appear under Settings > Passwords & Accounts rather than as a standalone section.

Which Password Do You Actually Need to Change?

The right answer depends on what prompted the question in the first place. Routine security hygiene, a suspected account compromise, a forgotten code, or simply setting up a new device each point toward different steps — and carry different stakes. Someone updating a rarely-used app password has a very different situation than someone who suspects their Apple ID has been accessed without permission, where speed and account recovery options become far more important factors.
