Password Strength & Security Checker

The Password Strength Checker analyzes passwords against modern cryptographic security benchmarks. It calculates information entropy in bits, estimates brute-force computational cracking time against modern GPU clusters (e.g. 100 billion guesses/second), and flags common vulnerabilities like dictionary words, repeating sequences, and predictable patterns.

1. 1Type a test password into the masked input field.
2. 2Click the eye icon if you wish to reveal the characters.
3. 3Review the entropy score (bits), crack time estimate, and strength tier.
4. 4Follow the security checklist to bolster weak credentials.

• •Aim for passwords with at least 60+ bits of entropy (14+ random characters or 4 random diceware words).
• •Use a dedicated password manager to generate and store unique credentials for every account.
