Better Password Security with Firefox

We all know how we should treat passwords. Use a mix of upper and lowercase letters, special chars and numbers. Choose longer passer passwords rather than short ones. Don't use the same password everywhere.

Well, you know that. I know that. But still, I was using two or three very insecure passwords on various websites again and again. Just because it's so much easier :-?. Until a few days ago.

Password Hasher Dialog That was when I discovered Password Hasher.

Password Hasher is a Firefox extension, helping you to make your passwords more secure.

The idea is simple: You continue to use your ridiculous simple password. But the extension creates a much more secure password from your silly password and the domain name of the login page. This secure password then is used to register and login at the page. This solves multiple problems:

  1. The password is harder to break because it's longer and more complicated
  2. You don't have to remember the complicated password
  3. The password is unique for this single website, if the site is compromised your logins for other sites are safe

Usage is simple. Just install it and whenever there is a password field to fill, open Password Hasher by one of the following methods:

  • Right click the password field and choose the Password Hasher menu entry
  • or Press Ctrl+;
  • or choose it from the Tools menu
  • or click the little # button right next to the field

In the dialog enter your (silly) master password and click OK. Password Hasher will fill the secure password into the field and you can login.

But what when you need to login and don't have your own Firefox? Just use the JavaScript online tool at the author's website to create the secure password.
