If you need to change the phone number at which you receive 2FA codes or switch your 2FA method to Authenticator app, there are two ways to do that:
Disconnect your previous phone number on the Security page.
Request 2FA disable for your account.
I have access to my previous phone number/device
If you have access to the phone number that’s currently registered for receiving 2FA codes, you can change it in the Profile menu, under the Security tab. The same way users can add 2FA method using the Authenticator app method.
How to change the phone number for 2FA codes
Click Disable next to the Text Message option for 2FA
Read the security warning and click Confirm to proceed.
Authorize 2FA disable with the code sent to your phone number
Click Confirm to continue.
To re-enable 2FA with your new phone number:
Click Enable next to Text Message option for 2FA
Enter your new phone number
Enter the 2FA code sent to your new phone number
That’s it! Now you’ll receive 2FA codes delivered to your new phone number.
