Use a Strong Passcode

Other than Face ID or Touch ID, the only thing that’s keeping people out of your iPhone is your passcode. While no one else has the same face or fingerprints as you, they can still get into your iPhone if they know the right code.

Because of this, it’s best to create a really strong passcode that’s hard to guess or crack. That means staying away from easy sequences like 000000 or 123456. Not only will your iPhone suggest those are really weak passcode, but those are the first numbers someone will try to use to get into your iPhone. You should also avoid numbers that are easily associated with you, such as your birthday.

If you do have an easy passcode, here’s how to change it:

1. Open the Settings app on your iPhone.
2. Scroll down and select Face ID & Passcode or Touch ID & Passcode
3. Enter your current passcode.
4. Scroll down and select Change Passcode.
5. Enter your current passcode.
6. Optionally, choose Passcode Options if you’d like to use a different format for your passcode, such as a numeric code that’s longer than six digits or an alphanumeric password.
7. Enter your new passcode or password and confirm it. 

We recommend using a really strong passcode that’s hard to crack. The harder, the better, even if it’s hard to remember at first. Ideally, pick an alphanumeric passcode; one of the benefits of Face ID and Touch ID is that you’ll rarely have to enter it anyway.
