Guide
Estimate password entropy (bits) and strength from length and character-set size. Passwords are not stored. Informational—leaks and reuse are out of scope.
2026 notes and common mistakes
Prefer long unique passwords plus a manager and MFA. A “strong” meter alone is not enough if the password is reused.
Tips
- Use a password manager.
- For information only—enable MFA where possible.
