I am a member of a non-profit that has multiple people checking and managing the emails. Somehow, it has locked onto my phone as the main login device. When someone else logs in at another location, I have to coordinate with them to get the codes, or it blocks their login completely. How do I make it so these individuals can also sign in at any location? Do I have to turn off two-step authentication? I would rather not do that, but I need others in the organization to be able to access the account regardless of location. Please advise.
