Common questions
Security Tools FAQ
Are generated passwords sent to ToolPool?
The password tools are designed to generate and assess values locally in your browser, without requiring the password itself to be sent to ToolPool.
What makes a password strong?
Long, unique, randomly generated passwords are generally stronger than short or reused passwords. A password manager can help you store a different password for every account.
Does a strong score guarantee a password is safe?
No. Strength checks are guidance, not a breach lookup or security guarantee. Never reuse passwords, enable multi-factor authentication, and replace any password you suspect is exposed.
