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).

Main learning re twitter was: > A phone number is sufficient to password reset a Twitter account even if not used as 2FA. Can completely remove phone from Twitter. I had seen the "phone numbers are insecure, don't authenticate with them" advice before, but did not realize this

I don't remember when I *added* the number; my guess is that it was required to sign up for twitter blue.

Using a phone number with 2FA is so bad, I send an email to USAA every year telling them to remove phone number 2FA on their site. TOTP, FIDO, or Yubikey... anything but phone number.

Everyday i learn more. Its like we need to take loss or something just so we are able to recognize the importance of anonymity. What would be the best way to have the 2FA? Or should we use more than 2 now🤔It's a challenge for me to provide informative information 4 others who are less willing to become decentralized

I think the best two-factor authentication is by using the authenticator app which uses 512-RSA grade rotating keys developed by EMC for highly secure government & enterprise environments (think NSA).

https://twitter.com/settings/account/login_verification 'Authentication app' or 'Security key' should be the only 2 options there. So far have had no troubles with using my 2fa app.

@vitalik.eth besides removing phone number as backup, I would also recommend to 'lock' your account with T-mobile. It's more painful to switch eSims, but it gives you much better protection. I also suggest to add passcodes for messengers like Signal, Telegram and Whatsapp.
