Frequently Asked Questions
How is the strength measured?
It looks at length, the mix of character types, and common weak patterns to estimate how hard the password would be to guess.
Is a high rating a guarantee?
No rating can promise safety, but a strong rating means the password is far harder to crack than a short or simple one.
Should I paste a real password?
It is safe here because nothing leaves your browser, but never paste a real password into a tool you do not trust.
Is anything sent to a server?
No. This tool runs entirely in your browser, so the values you enter, including any secrets, never leave your device.
Is it free?
Yes. Every tool here is free to use with no sign up.
