A password generator in your browser's toolbar. Copy a password, or right-click any field on a sign-up form and Roll fills it in. Passwords are never saved to disk or sent anywhere.

What it does

Five kinds of password: random, passphrases from words, PINs, patterns for sites with strict rules, and passwords you can say. Numbers and symbols can stand in for the letters they look like.
An honest strength meter: bits of entropy from how the password was made, and how long it would take to guess.
Copy it in one click, or right-click any field and choose “Generate password here” to fill it, so your browser offers to save it.
Presets for strong, Wi-Fi and old-site passwords, passphrases and PINs, plus your own. Default is always your last-used settings.
Spell it out shows a password character by character, so you can read it aloud or type it on another device.
Check a password you already have, with an optional breach check that sends only the first 5 characters of its hash.
Nothing is stored or sent: no account, no history, no server. Anonymous usage counts only if you say yes.

Where it runs

It's a browser extension for Chrome, Edge, Brave and Firefox on a computer, one click away in the toolbar.
