Zoom Meeting Administation

I am a host for our weekly DA meeting. We have an admin, and when I start the meeting, I use his credentials (email and password) to sign into the meeting.  However, I sometimes get a  message that Zoom doesn't recognize the device. It sends a "code" to the admin. The problem is that the admin is not always available when the meeting starts.! Argghhh. Is there some way that the code can be sent to me as the host? Or, maybe can we have a backup admin? Really appreciate your help. Thanks.
