Enabling two-factor authentication is a simple and effective way to beef up the security of your online accounts. Also known as 2FA, it introduces an additional step in the log in process, which typically requires the user to enter a code received via SMS or retrieved from an app, after their password is validated.
To take advantage of two-factor authentication the services that you use have to offer this feature, which is not always the case. But, as far as Twitch is concerned, two-factor authentication is no longer missing from the options.
The popular video streaming service has announced, on its blog, the arrival of two-factor authentication, encouraging users to turn the feature on. The implementation is similar to other services, meaning that the security code will be sent via SMS.
Alternatively, users who have Authy accounts can also use this app to get security codes. This method is better suited for cases when users are roaming or they don't wish to use such information via SMS. The security code is delivered in a push notification from Authy, which means that a data connection is still required.
The feature can be enabled by accessing the Security menu under Twitch Settings, and selecting the "Enable Two-Factor Authentication" option. Users are required to enter their password prior to it being enabled, and a phone number.
