API-Friendly Password Strength Checker — How It Works

API-Friendly Password Strength Checker — How It Works

Produces clean, structured output that’s easy to pipe into scripts or APIs. This tool scores a password based on length and character variety, and suggests specific ways to make it stronger.

What it checks

  • Length — longer passwords are exponentially harder to brute-force.
  • Character variety — lowercase, uppercase, numbers, and symbols.
  • Common patterns — very short or simple passwords score low even with variety.

Tips for a strong password

  • Aim for at least 12-16 characters.
  • Mix uppercase, lowercase, numbers, and symbols.
  • Avoid dictionary words, names, and predictable patterns like “123” or “qwerty”.
  • Consider a password manager so you don’t need to remember complex passwords.
