Use a passcode with your iPhone, iPad, or iPod touch

Learn how to set, use, and change a passcode on your iOS device.

Set a passcode on your iOS device to help protect your data. (If your device supports Touch ID, you can often use your fingerprint instead of your passcode.) Then your device will require your passcode when you do the following:

  • Turn on or restart your device
  • Slide to unlock your screen (you can change this)
  • Update your software

  • Erase your device
  • View or change passcode settings
  • Install iOS Configuration profiles

Set up a passcode

  1. Go to Settings > Touch ID & Passcode. On devices without Touch ID, go to Settings > Passcode:
  2. Tap Turn Passcode On.
  3. Enter a six-digit passcode. Or tap Passcode Options to switch to a four-digit numeric code, a custom numeric code, or a custom alphanumeric code.
  4. Enter your passcode again to confirm it and activate it.

Change your passcode or passcode settings

Go to Settings > Touch ID & Passcode. On devices without Touch ID, go to Settings > Passcode.

You'll find several settings and options:

  • Turn Passcode Off: Tap this option to turn off your passcode.
  • Change your passcode: Enter a new six-digit passcode. Or tap Passcode Options to switch to a four-digit numeric code, a custom numeric code, or a custom alphanumeric code.
  • Require Passcode: By default with this setting, as soon as you lock your screen, you need to enter your passcode to unlock. If you don't want an immediate passcode requirement, change this setting (For your security, if you use Touch ID or Apple Pay, you can't change the immediate passcode requirement).
  • Allow Access When Locked: Use this option to allow access to some features when your device is locked, including Notifications View, Siri, and Control Center.
  • Erase Data: Choose whether to erase your device automatically after ten failed passcode attempts.

Follow the steps in this section for help with things like passcode settings, alerts, and forgotten passwords.

If an alert says to change your passcode or you can't adjust your passcode settings

Configuration profiles and email accounts based on Microsoft Exchange (common with business or education devices) sometimes have passcode policies that cause issues like this:

  • You can't turn off your passcode.
  • You can't change passcode settings because they're unavailable, gray, or dimmed.
  • You see an alert that asks you to change your passcode.


Contact your IT administrator for help. If you don’t use a configuration profile or Microsoft Exchange account, or if your device is personally owned, contact Apple Support.

If you forgot your passcode

If you or someone else enters the wrong passcode too many times, your device will disable itself temporarily. If so, get help with a forgotten passcode or disabled device. Or, if you forgot your Restrictions passcode, learn what to do.
