Password Generator help

Generate strong passwords or memorable passphrases entirely in your browser.

Password

• Set the length and which character classes to include.
• "Avoid look-alike characters" removes l 1 I O 0 o and a few quotes.
• At least one character from each selected class is always present.

Passphrase

• Picks words at random from a built-in list, joined by your separator.
• Capitalise each word and add a trailing number for sites that demand a digit.

Strength

The bar shows a rough entropy estimate in bits: under 40 is weak, 60+ is strong, 80+ is very strong. It assumes the attacker knows your settings and only has to guess the random choices.

Notes

• Randomness is from crypto.getRandomValues. Nothing is generated on or sent to a server.
• Your options are saved in your own browser, but generated values are not stored anywhere.

Everything runs in your browser. Nothing you enter or drop is uploaded.
