These are the 20 most common phone PINs: Is your device vulnerable?

(Pocket-lint) - Is your phone PIN "1234"? No? What about "0000"? Believe it or not, these are two of the most popular phone passcodes people use.

Tarah Wheeler, a cybersecurity expert, revealed the 20 most common PINs used by mobile phone users to secure their devices. The data was compiled in 2019 by an InfoSec expert via the SANS Institute. If you want more recent data, a German-American team of IT security researchers investigated the most common four-digit and six-digit PINS and presented the results at the IEEE Symposium on Security and Privacy in 2020.

Here's a look at all their findings, plus how to change your PIN on iOS and Android devices.

These are the 20 most common phone PINs: Is your device vulnerable?

Most popular mobile phone PINs

According to Wheeler, 26 per cent of all phones are cracked with these 20 four-digit passcodes:

Philipp Markert, Daniel Bailey, and Professor Markus Durmuth from the Horst Gortz Institute for IT Security at Ruhr-Universität Bochum conducted a study jointly with Dr. Maximilian Golla from the Max Planck Institute for Security and Privacy in Bochum and Professor Adam Aviv from the George Washington University. They found the 10-most popular four-digit pins as well as the 10-most popular six-digit pins.

While many of these make sense, some of them are real head-scratchers, such as the "1004" one toward the top of the list. Why that sequence?It's certainly an enlightening look into people and their PIN choices - and if your passcode is on the list, we suggest changing it now.


How to change your mobile phone PIN

If your PIN is on the above list, you should be concerned about the vulnerability of your device. You should immediately change your passcode.
