You can easily enable or disable any two-factor authentication (2FA) methods from your mobile or desktop app. 2FA is only available for 2FA Protected accounts.
Tip: If you would like to change an existing 2FA method (e.g. change your email 2FA to a different email address), you will need to disable the method and then enable it again.
