Password Generator

Choose a length and the character sets you want: lowercase letters, uppercase letters, digits, and symbols. The generator builds a new string in this browser with crypto.getRandomValues.

The page does not store the result after you leave or refresh. Copy it into a password manager if you need to keep it. Two Generate clicks are not expected to match.

Password questions

Is the password stored on a server?

No. The string is built in this page. The site does not keep it after you leave or refresh.

Why do two Generate clicks differ?

Each click draws new bytes from crypto.getRandomValues. Matching draws would be a surprise, not the design.

What if I turn off every character set?

You get an error asking for at least one set. The generator will not invent an alphabet.
