Overview
This tool scores your password using length, character diversity (upper, lower, numbers, symbols), rough entropy, and simple heuristics for predictable patterns. It also flags a small set of extremely common passwords. It does not scan breach databases or transmit your password — feedback is generated locally in your browser for responsiveness.
Longer passwords usually beat “clever” short ones. Mixing character types increases search space for attackers. Avoiding keyboard walks, repeated chunks, and widely-used phrases reduces guessability. For important accounts, prefer unique passwords stored in a password manager plus two-factor authentication where available.
The generator uses your browser’s random source to build a mixed character password. Copy it directly into a password manager or trusted sign-up flow. Do not share generated passwords in chat or email, and rotate credentials if you suspect exposure.
