authentication for multiple accounts in one place without having to provide
your phone number.

   select Use an Authenticator.

Log in to Webmail with multi-factor authentication

   authentication app.

authentication in your account settings.

      type configured for password recovery.
   3. If you select Off, multi-factor authentication is immediately
      disabled.

Reset multi-factor authentication

You might need to perform these steps if you want to change your
authentication method or set up a new device.

   the previous sections for instructions to set up your preferred
   authentication type.

Manage multi-factor authentication on linked devices

If you access your Rackspace Webmail account on multiple devices, you can
manage which devices are trusted and no longer receive a prompt for
multi-factor authentication when you log in. You can also remove devices from
the trusted list.

1. Log in to Rackspace Webmail.

2. Open the Webmail settings page and select Security.

3. In the Trusted Devices section, you can see a list of trusted devices
   associated with your email account.

   You can remove devices that you do not recognize or no longer use by
   clicking the trash icon.

   

If you remove a device from the Trusted Devices list, you must use
multi-factor authentication when you next log in to your account on that
device.
