How to Test Password Strength
01. Type or Paste
Enter any password or passphrase into the input field to evaluate its security posture.
02. Inspect Entropy & Crack Time
Review real-time mathematical entropy bits and estimated time required for high-speed GPU clusters to brute force.
03. Follow Suggestions
Apply recommendations like removing dictionary words, adding special symbols, and extending character length.
