What is two-factor authentication?
Two-factor authentication keeps your account more secure by requiring both your password and your phone to login.
When you log in with two-factor authentication enabled, you will need to enter both your password and also a unique code generated on your phone. This provides a second layer of protection on your account. Even if someone knows your password, they won't be able to access your account without also having your phone.
Please log in to your account and go to your Profile Page to set up two-factor authentication for your account.
