10 Most Common 4-Digit PINs Revealed: Change Yours Now If It's On The List

Choosing simple or PINs that are easy to crack significantly increase the risk of unauthorised access to personal accounts and sensitive information. Jake Moore, a cybersecurity expert from ESET, strongly advises against using such passcodes. He notes that many people underestimate the risk until they fall victim to a cyber attack. Moore emphasises that skilled hackers can crack a significant portion of passcodes within a limited number of attempts, making it crucial to avoid using birth years, personal information, or repeated patterns for personal accounts, including social media.

The study also highlighted some of the least common 4-digit PINs, which offer better security:

• 8557

• 8438

• 9539

• 7063

• 6827

• 0859

• 6793

• 0738

• 6835

• 8093

Despite these precautions, passcodes can still be vulnerable to hacking. Therefore, Moore suggests using password managers for enhanced security. These tools can safeguard personal information by generating completely random codes, reducing the reliance on memorable, but insecure options like birthdays or anniversaries.
