There are various ways to log in to your account. But as security threats increase, so does the need for stricter account security measures. (Two) 2-Factor Authentication (2FA) is a login process that provides extra security to your account even if your password is compromised.
Once you put in your user name and password, you will be required to type in a one-time password that is generated by an authentication app (e.g. Google Authenticator) on your mobile phone.
This password changes every time you try to log in.
