How to change your two-factor authentication—after having established 2FA previously
Sign into the ETHERFAX Client portal at https://clients.connect.etherfax.net.
Once signed in, click on your arrow near your username in the bottom-left corner, and then click Manage Two-Factor:

Since Two-Factor Authentication was set up prior, one option will be Enabled while the other is Disabled.

(Optional) Selecting Manage on the Authenticator App method allows you to set up a Backup Mobile Phone in case a reset is needed.

Re-scanning the QR Code and verifying once again will replace the previous 2FA that has been established for the one you have now just established. Adding a backup mobile phone number does not change the previous 2FA.
Choosing to change your 2FA method, follow the instructions on screen after clicking SET UP NOW on the alternate option.
You have now successfully changed your user’s two-factor authentication!
