AI doesn't just guess passwords anymore; it is learning them. Passwords that took hackers years to crack can now be cracked in seconds with machine learning models. Weak, short, or reused passwords are essentially unlocked doors for AI-powered cracking machines.

AI Password Cracking in 2025: Key Findings

AI-powered password cracking has become dramatically faster in 2025, with 85.6% of common passwords now crackable in under 10 seconds[1]. This acceleration stems from two main factors: advanced AI models that learn password patterns and powerful consumer GPUs.

Hardware Advances

The latest consumer graphics cards, particularly the RTX 5090, have transformed password cracking capabilities. Hive Systems reports that a setup of 12 RTX 5090s is now used as the benchmark for modern password cracking attempts[2].

Time to Crack by Password Type

For bcrypt-hashed passwords (work factor 10):

  • 8 characters or less: Instant crack regardless of complexity
  • 10 characters with mixed characters: 27 years
  • 12 characters with mixed characters: 244,000 years
  • 16 characters with mixed characters: 19 trillion years[2:1]

AI’s Impact

AI tools like PassGAN have revolutionized cracking by:

  • Learning common password patterns
  • Recognizing user habits like capitalizing first letters
  • Predicting likely passwords instead of random guessing[1:1]

Security Recommendations

Recent findings emphasize:

  • Length over complexity (minimum 16 characters)
  • Use of password managers
  • Implementation of Multi-Factor Authentication (MFA)
  • Adoption of passkeys where available[3]

    Oh, AI has nothing to do with it. It grabs the RockYou password list and guesses a password based on frequency of use.

    This is nothing new.

    If they want to do something actually impressive how fast can they crack sha256 hashed passwords without rainbow tables. I will let them off and not require any salting.
