FAQ

How do you check password strength online?

Paste or type a password into this checker to review length, character variety, repeated patterns, and other simple local strength signals.

Does this password strength checker send passwords to a server?

No. The strength estimate runs in the browser, so the password is checked locally on your device.

What makes a password strength result better?

Longer length, a wider mix of character types, fewer repeated characters, and avoiding common or predictable patterns usually improve the result.
