Frequently Asked Questions
Is my password sent to a breach database?
No. This checker uses a simple browser-local heuristic and does not send the password to a server or check it against breach lists.
Can the strength score guarantee my password is safe?
No. It is an estimate based on length and character variety, with a few common-pattern checks. Use unique passwords and a password manager.
Is my input uploaded or stored?
