If you’re like most people, you probably have a 4-digit passcode on your iPhone. But if you don’t, there are a few ways to get one. Here are three tips:

  1. Look for a sticker on the back of your phone that says “4-digit passcode.”
  2. Look for a code in the settings of your phone, under “Privacy.”
  3. Use a computer or phone app to find the four digits of your passcode and enter them into the phone’s settings.
