Opt out of SMS 2FA fallback (two_factor_authentication.sign_in_fallback_sms)

[travispaul]

I have 2FA enabled, I have my recovery codes printed and physically backed up in multiple locations. I would like to opt out of SMS 2FA fallback due to the potential for SMS intercept and SIM swapping/hijacking.

There seems to be no way to disable SMS recovery in security settings, if there is a way, please advise.

Thanks

I figured it out, within your security settings, if you click “Edit” next to “Fallback SMS number”, and scroll down the page, there is an option to “clear” the phone number.

I don’t see any option to ‘clear’ my primary SMS from 2FA (secondary SMSalready removed).  I’d like to remove the primary SMS.  Any other suggestions?

According to official documentation if there is more than one MFA method, I can remove one by clicking on the menu and selecting "Remove" instead of "Edit".

I have two MFA methods set up: SMA and Security Keys. The preferred method is set to Security Keys. However, I see only "Edit" option in front of SMS method. There is no way to remove SMS method for me.

I went as far as trying to get and register a Yubikey, and have been unable to remove the SMS 2FA. I recently witnessed an attack by SMS hijack, so I'm upset that I physically cannot seem to do anything to disable this and that I don't have authority to remove a ****ing phone number from my own account.
