![]() ![]() ![]() Instead of using just a single factor to authenticate your identity, like a password, you use two different factors, usually your password and a one-time code sent via SMS or email.īy spreading the risk across two factors, it’s much less likely that an attacker will be able to unlock one of your accounts. Two-factor authentication - or two-step verification - is a security feature that adds an extra layer of protection to your online accounts. More commonly, 2FA is vulnerable to account recovery attacks and phishing schemes. Two-step authentication can be hacked through man-in-the-middle attacks, though this is becoming increasingly less likely.

As long as you have at least one of those devices available you will be able to authenticate with 2FA. You now have multiple devices configured for 2FA. For an Android device, install Aegis Authenticator, then click the menu icon in the top right, Settings > Import & Export > Import from file, choose Plain text as the file type and select the file. For another desktop use Gnome Authenticator again: Preferences > Backup/Restore, then under Restore select Authenticator and choose the file. Keep the file somewhere accessible from all devices, e.g. Under Backup select Authenticator to export to a plain text file. Click the menu item in the top right and select Preferences > Backup/Restore. Once all accounts are set up in Gnome Authenticator, export the keys to a file. Also keep a copy of the recovery keys for each account as you go. It will then import.Īfter setting up all accounts, go to the Pictures folder in your home directory and delete the screenshots. Select Screenshot and take a snapshot of the QR code. With Gnome Authenticator, click the add button in the top left, then in the dialog that appears, the Scan QR Code icon in the top right.

While the order does not matter, as both apps can import and export some common formats, here is a suggested approach: Aegis does not require Google Play Services, and is available from F-Droid, a catalog of free and open source software for Android phones (as well as the Google Play Store) Both support manual import and export of keys in de facto standard file formats so that keys can be shared between multiple devices. One option is to combine Gnome Authenticator on a Gnome Linux desktop with Aegis Authenticator on an Android phone. Unfortunately, Authy is also proprietary, and its Android app requires Google Play Services, so that it works only partly on Google-free phones such as the Volla Phone. As long as a user has at least one of those devices available, they can authenticate. Twilio Authy is a popular alternative with multiple device support, including mobile and desktop devices, with automatic synchronization of keys between them. While Google and Apple have their own proprietary 2FA solutions based on Android and iPhone devices, these create a dependence on a single device. As an emergency backup for the loss of the device, recovery codes are provided, or perhaps a manual process of identity verification. For online accounts these are typically a password (something the user knows) and a code demonstrating possession of a known device (something the user has). Two Factor Authentication (2FA) is a security paradigm whereby two pieces of evidence are required for authentication.
