Frequently Asked Questions
How secure are the generated passwords?
Passwords are generated using cryptographically secure random number generation. The entropy depends on the length and character set used. A 16-character password with all character types has approximately 95 bits of entropy.
Can I customize the password format?
Yes! You can adjust the length (4-128 characters), include/exclude uppercase letters, lowercase letters, numbers, and special characters.
Are passwords stored or transmitted?
No! All password generation happens locally in your browser. Your passwords are never sent to any server and are not stored anywhere.
What is a passphrase?
A passphrase is a sequence of random words used as a password. It is easier to remember than random characters while still being secure. For example: "correct horse battery staple".
