Frequently asked questions
Is this advanced password generator safe to use?
Yes. All passwords are generated locally on your device using your browser's Web Cryptography API. Nothing is sent to Doffl servers or stored anywhere online.
What makes a password cryptographically secure?
A cryptographically secure password uses high entropy, adequate length, and a pseudo-random number generator designed to resist prediction attacks.
Can I exclude ambiguous characters like 0 and O?
Yes. You can toggle options to exclude visually similar characters like 1, l, I, 0, and O to make manual transcription easier.
Do I need to create an account or pay to use this tool?
No. This password generator is completely free to use with no account registration or software installation required.
How long should my password be?
For standard accounts, a length of at least 16 characters is recommended. For master passwords or sensitive administration keys, use 20 characters or more.
