How this checker works
The checker looks at length, character variety, repeated characters, and common weak patterns. It is a helpful estimate, not a guarantee.
Typed passwords remain in the browser input only. They are not stored, transmitted, logged, or placed in analytics.
Improve a weak password
Make it longer, avoid dictionary words and personal details, add variety, and never reuse it on another website.
For important accounts, generate a new unique password and save it in a trusted password manager.
Frequently Asked Questions
Are generated passwords saved?
No. Generated passwords stay on your device and are never stored by ThePassKey.
Does the password checker send my password anywhere?
No. The checker estimates strength in your browser only. Typed passwords are not sent to a server.
Should I still use a password manager?
Yes. A trusted password manager helps you store long unique passwords safely for every account.
