Get started with two-factor authentication

Select your preferred method to receive confirmation codes for two-factor authentication.  Receiving a text message to your mobile phone is the default option.  Alternately, you can use an authentication app such as Duo Mobile.

2FA method

Enter the six digit code that was sent to your mobile phone via text.  This step authenticates you to make this change to your account.  Please note, the text message will come from a five digit number, for example 32665.  This is NOT the code.  The six digit code is in the text message itself.

Enter 6 digit code

Two factor authentication is now set-up on your Facebook account.
