Once standard 2-step verification is enabled, you can enable additional options for added security.
To enable the authenticator app, click on the Application Settings button in the top right of the platform:
This window will default to the Accounts tab so you would click on the 2-Step Verification tab followed by clicking “Set Up” under the authenticator app section:
Choose your operating software and click ‘Next’.
Then scan the barcode from your Authenticator App. Once the setup is complete, click ‘Next’.
Then enter the 6-digit code from the newly setup app and click ‘Verify’.
When signing in from a new device, you will still receive the email for approval. When clicking on Approve from the email, you will need to validate via your chosen method. Select ‘Authenticator app’.
Enter the code from the Authenticator app and click ‘Verify’. Once verified, the new device will be able to sign in and will be shown on ‘My Devices’ as a trusted device.
