    If an agent's phone number changes, how can I change it so they continue to receive the SMS 2FA codes?

  • Wilfred Kaw

    Hello @pstrauss,

    An Agent can make this change in their own profile by following this process:

    1) Select the Admin gear icon on the lefthand side of your Zendesk Support and choose People.
    2) Search your own name and select edit.
    3) Then select the 'Security settings' tab.
    4) Once there, choose 'Edit' under 'Two-Factor Authentication'
    5) Select Use SMS, and you'll be able to update the Two-Factor Authentication number.

    If 2FA is already enabled, but set to SMS, is there a way to switch only selected users to "use mobile app" or is this a global setting.  If it is switched over to "use mobile app"  would it force the users to register the app on next log on, or simply provide an option.

    Hello @...,

    Please note it is possible to have only one 2FA method, either SMS or the mobile app, not both.

    The agents need to specify which they want to use themselves when setting up their 2FA.

    If the 2FA method is switched from one to the other, the next time the agent signs on they would be forced to use that method.

    Whatever the method, when the agent chooses the method, they will either have to scan the QR code with the mobile app, or provide a telephone number in their profile for the SMS.

    Hope that clarifies!

    Given you already support google authenticator then there is a hardware token that can be used with zendesk - you can use a safeid/diamond token;

    The token is a programmable token so would be seeded using the same QR code you use when seeding the google authenticator app (you use an app on your phone or PC to program the token via NFC).  Once programmed it generates the same OTP codes the google authenticator produces but is then a fully independent and self-powered device.
