- prng2021 2y agoI just did some quick research on these IDs. Correct me if I'm wrong, but it seems like each user account would be tied to one device. It also seems like the user, at least on Apple devices, has to opt into advertising tracking in order for your app to even get access to this. Ignoring the security pitfalls of phone numbers, it really doesn't seem like these advertising IDs are a drop in replacement for using phone numbers.

But if somehow knowing that phone number is a key to getting your 2FA secrets, you'd have a bigger problem. Except it often is, and that's the problem.
- ezekg 2y agoDo what I do and turn off "allow multi-device." Problem solved -- even if your phone number is stolen, they can't recover your 2FA because it's locked to the device too.

- ezekg 2y agoYep. I've done this. Lots of people I know use "burner" phones without cellular for 2FA.
