Password Policy Tester

Test passwords against real site policies (Google, Apple, AWS, Naver, banking, etc.) and a custom ruleset with entropy estimation

How to use

  1. Type a password into the input field; the character count and entropy bits update instantly.
  2. Switch to the Presets tab to see whether the password passes common policy standards such as NIST, OWASP, or common enterprise rules.
  3. Switch to the Custom tab to define your own policy rules and check the password against them.
  4. Read the per-policy pass/fail matrix to identify exactly which requirements are not met.
  5. The password is processed entirely in your browser — nothing is stored or sent anywhere.

Examples

  • Entering MyP@ss1 shows 7 chars, roughly 40 bits entropy, and fails NIST length requirements but passes a basic complexity policy.
  • Entering a 16-character passphrase with mixed case, digits, and a symbol passes all preset policies and shows a high entropy badge.
