Phone passcodes – is yours easy to guess?

I saw someone’s passcode was set to one of the top easy-to-guess passcodes in the world so I promised the person I would provide instructions on how to update both the Android and iPhone passcodes in one of my articles.

The most common four-digit phone passcodes are simple, easy-to-remember patterns that are also easy for attackers to guess. The top passcodes include 1234, 0000, 1111, 1212, and 7777. If you have a six-digit passcode, the same concerns apply if you are using any patterns that repeat digits, use sequential numbers, or follow patterns along the number pad.

For iPhone:

iPhone Settings icon
  1. Go to Settings, then depending on your model, do one of the following:
    • On an iPhone with Face ID, select Face ID & Passcode.
    • On an iPhone with a Home button, select Touch ID & Passcode.
  2. If you have an existing passcode, it will ask for your current one.
  3. Select Turn Passcode On or Change Passcode.
  4. It will ask you again for your current passcode if you have one in place.
  5. Enter your new passcode if you want a 6-digit passcode. If you’d like a 4-digit, custom numeric, or custom alphanumeric code, select Passcode Options.
  6. Enter the new passcode a second time.

If you want additional protection, you can turn on Stolen Device Protection and Erase Data if there are 10 failed passcode attempts.

For Android:

Android Settings icon
  1. Go to Settings, then select Security. If you don’t find Security, go to your phone manufacturer’s support site to find the procedure for setting a passcode.
  2. Select Screen lock. If you’ve already set a lock you’ll need to enter your passcode, pattern, or password before you can set a different passcode.
  3. Select the screen lock option you’d like to use: swipe, pattern, pin, or password.
  4.  Follow the on-screen instructions to set a new lock option.
