      Tool description

      This checker provides a quick estimate using length, character variety, and pattern checks. For a stronger assessment, use a password manager and enable multi-factor authentication.

      How to use

      1. Paste a password to evaluate.
      2. Review entropy estimate and warnings.
      3. Improve length and randomness for better results.

      Why it’s useful

      • Spot weak patterns quickly.
      • Understand why “complex” can still be weak.
      • Get concrete steps to improve strength.

      Use cases & interpretation

      • Audits: evaluate internal password guidelines.
      • Training: teach length vs complexity trade-offs.
      • Personal: upgrade old weak passwords.

      FAQs

      It’s an estimate. Real-world safety depends on reuse, breaches, and how the password is stored/hashed.
