Frequently asked questions
Are generated passwords stored anywhere?
No. They are created in your browser with crypto.getRandomValues and are never sent or saved.
How long should a password be?
At least 16 random characters, or a passphrase of 5 or more words. Use a password manager to remember them.
What is entropy?
A measure of how unpredictable a password is, in bits. Each extra bit doubles the guesses an attacker needs; 80+ bits is very strong.
