Detailed User Guide
Generate cryptographically strong passwords
Passwords are created with the browser's secure random generator, not a predictable pseudo-random source, so they are suitable for real accounts.
Length matters more than complexity
A long password of random characters is stronger than a short one with symbols. Aim for 16 characters or more for important accounts.
Excluding ambiguous characters helps readability
Removing characters like 0, O, 1, and l makes a password easier to read aloud or type on a phone without meaningfully weakening it.
Generated locally and never stored
Passwords are created in your browser and are not logged or transmitted anywhere. Pair this with a password manager for safe storage.
Meet site-specific requirements
Many sites require a mix of uppercase, lowercase, numbers, and symbols. The character-type toggles let you satisfy those rules exactly.
