Two-factor authentication (commonly refered to as 2FA) is now available for snippet.host users. We are using OTP (One Time Password) as the authentication mechanism.
In order to activate it, go to settings > enable two-factor authentication and follow the instructions there. Remember to save the recovery code in a safe place - it is necessary to recover the account if you're no longer able to generate authentication tokens.
Here are some apps that you can use. They're all compatible with snippet.host. You can use any application that uses the OTP mechanism.
