How to change iPhone passcode

Set or change the passcode

1. Go to Settings , then do one of the following:

• • On an iPhone with Face ID: Tap Face ID & Passcode.
  • On an iPhone with a Home button: Tap Touch ID & Passcode.

1. Tap Turn Passcode On or Change Passcode.
2. To view options for creating a password, tap Passcode Options. The most secure options are Custom Alphanumeric Code and Custom Numeric Code.

After you set a passcode, on supported models you can use Face ID or Touch ID to unlock iPhone (depending on your model). For additional security, however, you must always enter your passcode to unlock your iPhone under the following conditions:

• You turn on or restart your iPhone.
• You haven’t unlocked your iPhone for more than 48 hours.
• You haven’t unlocked your iPhone with the passcode in the last 6.5 days, and you haven’t unlocked it with Face ID or Touch ID in the last 4 hours.
• Your iPhone receives a remote lock command.
• There are five unsuccessful attempts to unlock your iPhone with Face ID or Touch ID.
• An attempt to use Emergency SOS is initiated (see Use Emergency SOS).
• An attempt to view your Medical ID is initiated (see Set up and view your Medical ID).
