According to a study by Home Security Heroes, almost 51% of all common passwords can be cracked in less than a minute by AI. Furthermore, 65% of common passwords were cracked in less than an hour whereas 81% of passwords took less than a month.
The firm used an AI password cracker called PassGAN to run through a list of 15,680,000 passwords and then published the results.
What kind of passwords are ‘safe’ from AI
According to the study, passwords that have more than 18 characters are “generally safe against AI password crackers, as it takes PassGAN at least 10 months to crack number-only passwords. The study also revealed that it could take 6 quintillion years to crack passwords that contain symbols, numbers, lower-case letters, and upper-case letters.
How to keep your passwords safe
As per the security research firm, the easiest passwords to crack are the ones that are digit-only. Even a digit-only password with 10 characters can almost be easily hacked.
“A ten-letter password with only lowercase letters would take an hour to hack, while a ten-letter mixed-case password would take four weeks,” noted the report. If one uses a ten-character strong password using letters, symbols, and numbers, then it could take five years to decipher.
The firm also shared a list of factors that ensure your password strength is difficult to compromise:
- Use at least 15 characters.
- Have at least two letters (upper and lower-case), numbers, and symbols in the password.
- Avoid obvious password patterns, even if they have all the required character lengths and types.
