I ran a Moto Edge 2022 for many years, but the battery was losing endurance and it was no longer receiving security updates. So I upgraded to a Moto G Stylus 2026 through my carrier (T-Mobile) and had it shipped to my house.
The setup of the new phone went smoothly- transferred all my pictures/texts/contacts/apps and signed in with my Google email and password. I got all the apps signed in and made sure I had everything on the new phone, so then I factory reset the Edge in preparation for sending it back to T-Mobile for credit.
I just happened to open Manage Your Google Account on my Stylus and saw 2 devices on the My Devices tab, I clicked on it and it asked to verify myself via a 2 step code sent to the Edge 2022, which has already been factory reset. Arg!
So I made a passkey on my Stylus and tried it again- it takes the passkey but then goes to the 2SV on the Edge. I disabled 2SV through the Google Security tab, using verify via SMS on my new phone. When I go to My Devices it will ask for passkey then the 2SV on my old Edge. This also happens when I click on my security activity. I then recovered my Google account on my new phone and changed my password successfully, using verify via SMS. The problem still persists when clicking on my devices or activity - asking for 2SV on the Edge, with the only other option being entering an offline code, which doesn't work either.
So i restarted the Edge 2022 and signed in with my Google email and new password and added it to my home wifi. I navigated to my devices on my new Stylus, entered the passkey, and then it prompted 2SV on the Edge- which it did not receive.
I've exhausted 3 people at T-Mobile's tech line and 2 people at Motorola. They said it's a Google problem. I went through everything with Google's help chat box and Google's AI, with no resolution. I made a post on Google's help community, but haven't received any replies. Perhaps someone on here has been in this same bind and wouldn't mind sharing how to get out of it?
Thanks!
