Need Help With One Time Passcodes

Furnish Finders drives us crazy with all of the one-time passcodes they need. Every time we move from one section to the other, they want a new passcode.

Is there any setting that will prevent this from happening?

Is there any setting that will allow both I and my husband to receive these passcodes? Right now when he wants to login he has to ask me a million times for all of these passcodes.

It’s getting very frustrating. Anyone else having this problem and how have you solve it?
