About Password Strength Checker
A password strength checker helps identify obvious weaknesses before a password is used. Length, variety, and predictability all matter. Short passwords, reused phrases, keyboard patterns, names, and dates can be guessed faster than people expect, especially after credential leaks.
This checker runs locally and evaluates basic signals such as length, lowercase and uppercase letters, numbers, symbols, and common weakness patterns. It is not a breach database lookup and does not send your password anywhere. Treat the score as practical guidance, not a mathematical guarantee.
The safest workflow is to generate a unique password with a password manager. Use this tool when reviewing a manually created password or explaining why a credential policy rejects a value.
