Strength signals beyond "complexity rules"
Corporate policies often mandate symbols yet allow eight-character passwords that crack quickly. This checker emphasizes length and unpredictability over checkbox compliance so teams can align with NIST-style guidance.
Pattern traps
Appending ! to Password1 satisfies naive regex rules but not attackers with hybrid dictionaries. Passphrases of four or more random words typically outperform short "complex" strings.
Pre-deployment policy checks
Product teams can sanity-check generated defaults or reset flows before shipping. A meter helps UX copy explain why a rejected password failed without revealing server-side rules exhaustively.
