I get these alerts all the time. It is from logging into the store at work, which is 30mils away from my home, and then logging into the store or mog station at home. I just bounce between 2 passwords.

I dont think the $15 token is worth it enough to stop these alerts. I will only if it gets triggered from not my actions.

As for the software app, that thing deactivates every day because I have Google Fi and the developers required detecting your cell phone provider. So, removing the auth app and then adding it has caused me to be locked out because you cannot remove the mfa more than once in a 24hour period. So, I stop using it.
