3
Copy the password
Generate one or several passwords, then copy the one you need.
Why use this tool
Secure randomness
Uses crypto.getRandomValues with rejection sampling, not Math.random.
Strength and entropy
See the estimated entropy in bits and a strength label for the current settings.
Never leaves the browser
Passwords are generated locally and never stored or transmitted.
Frequently asked questions
How long should a password be?
Use at least 16 characters for important accounts, and prefer a unique password for every site. Length matters more than complexity.
What does entropy mean?
Entropy measures how many guesses an attacker needs. It is length multiplied by the log base 2 of the alphabet size, measured in bits.
Why exclude ambiguous characters?
Characters like I, l, 1, O and 0 look similar in many fonts. Removing them reduces typing mistakes, at a small cost in entropy.
Are these passwords stored anywhere?
No. They are generated in your browser and disappear when you close the page. Save them in a password manager.
Can I use symbols like spaces?
This generator uses a common symbol set without spaces so the password works in most forms. A password manager handles any character you choose.
