That was my reaction.

A tenant can be set up to expose the “don’t ask me to sign in again on this device” option, and to let the MFA last for a certain amount of time. It would be worth reviewing your tenant config. MFA shouldn’t be as big a pain as people are making it out to be here. If it is, it’s either been set that way deliberately (security concern) or accidentally.

I don’t get recurring Authenticator requests on my phone. On desktop, I use a different browser profile for each tenant I have admin rights to and sign in with accounts specific to those tenants. MFA requests are very rare.

If you’re using a single account to hop between tenants (like a MS partner acct), in a single browser session, it’s very messy and requires you to pay very careful attention to which tenant you happen to be in. I don’t advise this approach.
