Frequently asked questions
Common questions about the Password Generator.
How does Password Generator work?
Choose length and character sets, then generate. Passwords are created with crypto.getRandomValues in your browser. You can copy, download as password.txt, show/hide, or regenerate.
Does my password leave my device?
No. Generation stays in your browser. ToolsArk does not upload passwords or call a remote generator API.
What options can I control?
Length from 4 to 128 characters. Toggle uppercase, lowercase, numbers, and symbols. Optional rules exclude similar characters, exclude ambiguous punctuation, avoid consecutive repeats, and require at least one character from each selected set.
How should I read the strength meter?
Strength is estimated from length and character-pool size (entropy), plus an illustrative offline crack-time at a fixed guess rate. It is not a full password-breach or pattern analysis, and it does not know if a password was reused elsewhere.
Is this safe for real accounts?
Use a unique password per account and store it in a password manager when you can. Prefer longer passwords with mixed character types. ToolsArk cannot guarantee that any password is unguessable against every attacker.
