During the 2FA set-up process, you will be given 2 options: to set up using an Authenticator app or using SMS Text message. If you choose "Authenticator app", you will be given a QR code which you need to scan using your chosen authenticator app to complete the set-up process:

To enable authentication app 2-factor authentication for your individual account:

1. Click on your account icon in the top-right corner of the page, and select Account Settings.
   


2. Under the Account tab, scroll to the 2-Step Verification section. (Note: You will not see this section if your organization uses single sign-on (SSO) for authentication.)


3. Click Set up.


4. Select Authentication App (recommended) and click Next.


5. Open the authentication app on your phone and scan the QR code. (You can also enter the secret key located under the QR code into the authenticator app manually.)
