About this tool

How to use
- Choose the length and character types.
- Check the strength shown.
- Copy the password.
Common problems and fixes
A site rejects symbols
Untick “Symbols” and increase the length to keep the same strength.
The password is hard to type
Tick “Avoid ambiguous characters” (0/O, 1/l).
I cannot remember them all
Use a password manager: it remembers and fills them for you.
Frequently asked questions
Is the password sent or stored?
No. It is generated by your browser (crypto.getRandomValues) and never transmitted.
Which length should I choose?
At least 16 characters for an important account; use a password manager to remember them.
What is entropy?
A measure of how hard the password is to guess: above 80 bits it is out of reach of known attacks.
Why not reuse a password?
A single leak would unlock all your accounts.
