Did you setup Twilio keys before it (Studio->Settings->Twlion area). If not then UNA can't send your SMS. You need to run this MySQL query:
UPDATE `sys_options` SET `value`='' WHERE `name`='sys_account_activation_2fa_enable';
Then clear the content of the folder "cache" (but don't touch .htaccess file there). After this steps, you will restore the situation before enabled 2FA option.
Hello Fabio!
Did you setup Twilio keys before it (Studio->Settings->Twlion area). If not then UNA can't send your SMS. You need to run this MySQL query:
UPDATE `sys_options` SET `value`='' WHERE `name`='sys_account_activation_2fa_enable';
Then clear the content of the folder "cache" (but don't touch .htaccess file there). After this steps, you will restore the situation before enabled 2FA option.
In the future we will not activate 2FA until Twilio settings are entered:

It has been just disabled.
