Currently, you probably either have…
- a different password for each website to which you have membership.
- a handful of passwords, some more secure than others depending on the type of websites they are for.
- one password for all of the websites that you are a member of.
In the first and second instance, purely due to the volume, there’s a good chance that these passwords are written down somewhere. This is bad.
In the third instance, you are opening yourself up to lots of problems if your single password is compromised.
PwdHash is a solution that allows you to have a different password for each of the websites that you are subscribed to, whilst allowing you to remember just one. It does this by creating a hash based on your ‘password’ and the url of the site you are visiting.
It is perfectly possible to do this manually and use a desktop app or command line tool to generate the hashed password for a given site. However, this would be a real pain if you are constantly visiting different sites that require authentication. The firefox plugin with this service basically takes the pain out of this manual process. Once installed, just press F2 or enter @@ in a password field and the hashed password will be created before submitting to the site.
