Use one password for everything, securely!

PassGrinder takes your one master password and generates a twenty-character strong password based on the website URL, domain name, app name, or unique phrase you choose. Your PassGrinder password is generated in your browser—it is never saved by this website. PassGrinder is designed to make it easy for you to use strong, unique passwords online. Go ahead, try it!

It is recommended to use the website URL, domain name, or app name where this password will be used to grind your master password into something more unique.
You may want to use a variation if you are required to change your password without needing to change your master password or unique phrase.
