- It cannot make a password easy to remember.
Frequently asked questions
How are the passwords made?
Each character is picked with the browser's cryptographic random generator, using a method that does not favor any character. The tool also guarantees at least one character from each kind you tick.
How long should a password be?
Longer is stronger. For accounts you do not need to type often, 16 characters or more from a password manager is a common choice.
Are generated passwords stored or logged?
No. They exist only in this page until you close it.
