Over 25% of phones can be cracked just by using one of the top 20 most used four digit PINs.
Cyber security expert Tarah Wheeler shared a list of the most popular PINs based on the findings of the folks at the SANS Institute, which is one of the largest cyber security organizations in the world. Some of the passcodes on the list aren’t surprising but there are a couple combinations that we didn’t expect to see.
Make sure your PIN didn’t make the list:

If your passcode made the list you should probably definitely change it ASAP. We’d recommend changing it to a 6-digit code too so that it’s even harder to crack with a brute force attack or just someone trying to lurk onto your iPhone.
To change your passcode, open the Settings app, go to Face ID & Passcode, scroll down to “Change Passcode.” You’ll have to enter your old passcode first and then choose another one.
