Strong password generator and password strength checker

Generate random passwords with upper and lower case letters, numbers and symbols, and leave out look-alike characters. Check the strength of a password you already use, right on your device.

How to use

Choose the length and the character sets to use.
Turn on "skip look-alike characters" if the password has to be read out or typed by hand.
Copy the password and save it in a password manager. To check an old password, type it into the check box.

Frequently asked questions

Are generated passwords stored anywhere?

No. The tool runs entirely in your browser and sends nothing anywhere.

How long should a password be?

At least 12 characters, and 16 or more for important accounts like email, banking and website admin. Length matters more than unusual symbols.

Can I use one password for several accounts?

No. When one site leaks, attackers try that password everywhere else. Use one password per account and keep them in a password manager.
