Good passwords are hard to invent and easy to forget, which is why most people reuse one weak password everywhere. This free password and passphrase generator fixes that: it creates strong, random secrets for you in seconds, right in your browser.
Choose Random password and set a length. Sixteen characters with upper and lower case letters, digits, and symbols is a solid default. The generator uses your browser secure random number source, not a weak pattern, and it guarantees at least one character from each group so the result is never all letters.
Or choose Passphrase. A passphrase is four or more random words joined by a separator, like river-stone-candle-garden. It is long, so it is hard to guess, but it is made of real words, so it is far easier to type and remember than a jumble of symbols.
Why does randomness matter? Attackers do not guess passwords one by one by hand. They try huge lists of common passwords and patterns. A truly random password is not on any list, and a long random passphrase has far too many combinations to try. Length plus randomness is the whole secret.
Everything here runs on your device. The generated password is never sent to a server, never stored, and never logged. For the strongest setup, generate a fresh password for every site and keep them in a password manager, so you only have to remember one master password.
Two habits complete the picture. Turn on two-factor authentication wherever a site offers it, and never share a password by email or chat. A strong password plus a second factor stops almost every common account takeover.
Press Generate as many times as you like until you get one you are happy with. It is free, needs no sign-up, and your passwords never leave your browser.
