An updated version of the classic Password Hasher add-on compatible with the new Webextension-API.
- Install the Firefox add-on
- Check the global add-on-settings
- Open a login page with a password field
- To open the hasher do one of the following:
- Click on the password-hasher-icon in the address-field of your browser
- Use the keyboard-shortcut Ctrl-Shift-F6
- Click on the "#"-symbol in or near the password-field
- Use the right-click contextmenu on the password field to open password-hasher
- Enter your master-key
- Click ok or enter: Done!
The hasher is generating a unique password for every site you visit. This works simply by creating a so called hash from the site-tag and your master-key. The site-tag is extracted of the domain and stored so it stays the same on every visit of this site. Together with your master-key (which is not stored) this results in a reusable hash:
You are visiting the login-page of https://www.github.com. The site-tag github is extracted from the domain. Now you enter your master-key.
site-tag: github
master-key: password
resulting hash: fnD'7ayb4nATjvdX
The resulting hash is now used as password for your github login. Now you are moving on to another website https://www.heise.de. The extracted site-tag becomes now heise. By entering the same master-key you'll get a different hash:
site-tag: heise
master-key: password
resulting hash: 0"Ajd0PqrldvYjeA
Bam. Different passwords for every site. You only have to remember your master-key which is never stored anywhere.
