Why does my iPhone need a passcode?
Without one, anyone holding your phone can open your email, bank and photos. Set a 6-digit passcode or longer in Settings, Face ID & Passcode.
Why It Matters
A passcode also locks the data on your phone, so it stays scrambled if the phone is lost or stolen.
What To Do
- Go to Settings > Face ID & Passcode. On iPhones with a Home button, it's Touch ID & Passcode.
- Tap Turn Passcode On, or Change Passcode if you have a short one.
- Use 6 digits or more. Tap Passcode Options for a longer code.
- While you're there, turn on Stolen Device Protection.
