Frequently Asked Questions
How secure is the generated password?
Each character adds entropy based on the size of the selected character pool. A 20-character password with all character types enabled is computationally infeasible to brute-force.
Are the passwords stored or transmitted?
No. Passwords are generated and displayed entirely in your browser and are never sent to any server.
Can I generate multiple passwords at once?
Click Generate repeatedly to get a new password each time. Bulk generation is not supported in this version.
Does it check for duplicate characters?
Not by default, but you can re-generate until you get a password that meets any personal criteria you have.
