The word “password” on an iPhone can mean several different things. Your Apple Account password protects your Apple services, your device passcode unlocks the iPhone, and saved website passwords are managed separately. If you want to change the password for your Apple Account, use the Sign-In & Security settings.
How to do it
- Open Settings and tap your name.
- Tap Sign-In & Security.
- Tap Change Password.
- Authenticate with your iPhone passcode or other requested verification.
- Enter and confirm the new Apple Account password, then follow the onscreen instructions.
If you meant the iPhone passcode
Go to Settings > Face ID & Passcode, or Touch ID & Passcode on an applicable model, enter the current passcode, and choose Change Passcode. A device passcode is not the same as your Apple Account password.
If you meant a website password
Current iOS versions include the Passwords app for saved website and app credentials. Open Passwords, choose the account, and use its change-password option to visit the service and update the credential.
Before you finish
Menu names can change slightly between iOS releases, iPhone models, carriers, and app versions. If your screen does not exactly match these instructions, install available software updates and look for the same feature under the closest matching Settings section. Avoid changing unrelated security, privacy, or account options simply to make a missing control appear.
After making the change, test the feature once so you know the result is what you expected. If the setting affects an account, cellular service, privacy protection, or device security, keep your account credentials and a recent backup available before doing additional troubleshooting.
