Go to My Account and click on ‘Manage Account’ (Under your profile). (See screenshot 1 below)
Scroll down, and you will see ‘External 2FA TOTP’, click on ‘Enable.’ A QR code will pop up along with the instructions.
IMPORTANT: Just below the QR code you will see a link (Click here to copy the key). Click on that link to copy the key & save it somewhere. We will need this later.(See screenshot 2 below)
Open any of your Authenticator Apps (such as Google Authenticator, Microsoft Authenticator, Authy, etc.) on your smartphone.
Click on ‘Scan a QR code’ under Add an Account Section and allow access to the phone camera.
Enter your 4 digit PIN first. Scan the QR code displayed in the My Account; a 6-digit TOTP will be generated (Valid for 30 Days).
Click on Enable; your TOTP will be set up successfully.
Note: Only once you have enabled TOTP, then proceed with next steps.
