Finally got back my T-mobile account (yes, it was a sim swap, meaning that someone socially-engineered T-mobile itself to take over my phone number).

Why aren’t you using an authenticator app or security key?

I am for most things; I don't think that was an option at the time that I last changed my twitter settings.

Ahh i see. It’s an option for Twitter and most other social apps now. 

Maybe we need to build an authenticator app based on a wallet address.

This is why you should remove your phone number from your twitter account

Importantly, even if you're using a more secure authenticator for Twitter, it can still be bypassed with the phone number using the account recovery flow.
