If only it was tied to the SIM, it's actually tied to the software installation, if your phone software gets reset it also decouples your 2 factor checks.
Its a pain
Thank you very much for commenting @paradigmprospect :)
nice to see someone else who also likes old phones
I have no reason to doubt what you're saying, I'm afraid I just don't get it yet.
Does that apply to old phones? You know, Samsung ones with built in spelling mistakes in their auto correct. Long before operating systems. I wouldn't even know how to reset that phone "software" - there's no real port or OS. And the number the verification arrives at is on my SIM, I can put the card in other phones and it will have the same number.
Isn't it true that as long as I have the same number on that old phone it will still work after resetting? How would the exchange know that anything is different? How would the phone not tie to its SIM number after rest? Because "modern" phones work differently and require OS shenanigans to access the actual number?
You don't actually need to answer these, just thinking out loud here, pondering how to best protect the access. I have had some hardcore password lessons in the last years that taught me a lot.
I know a few people who religiously reject smartphones <3
