The codes you need can be generated by an app you install on your mobile device as well as an app you have on your desktop. Scores of websites, online services, and apps offer improved account security using two-factor codes.
The idea of 2FA (as the cool kids call it) is that should anyone steal or crack your password they can’t use it in isolation as the requirement for a secondary code, which, in some cases, has to be generated for every new login, creates a hurdle a would-be rogue has to clear without you being notified. Think of it like needing two keys to your apartment: one to open the door, and one to prove it’s you who wants to get in. Two-factor authentication is one of the best way to secure your online accounts as it requires you to “authenticate” twice when signing into a service, app or site: once with your regular user password second with a time-limited code generated by an authentication app or sent to you via SMS.
In this post I take a quick look at what two-factor authentication is, why it’s (highly) recommended, and how Authenticator makes using the codes it creates seriously simple. If a service listed on that website supports ‘software tokens’ then it will work with it. For a simple, straight-forward way to generate two factor authentication codes on Ubuntu and other Linux desktops try Authenticator.Ĭreated by developer Bilal Elmoussaoui, ‘ Authenticator‘ is a GTK app you can use to get secure two-factor authentication codes to use with more than 200 providers, including GitHub, Microsoft, Twitter, Facebook, Google, and Dropbox.Īnd if you want to know if this apps supports a particular service before you install it search for it on the 2fa.directory.
