hello, i tried to log in from my phone today (not a recongnized device) so i knew i'd have to put the 6digits code, thing is, i never recieved the message on my phone ?!! also tried to do the email as try another method suggests, also didn't recieve an Email, now i changed the number to my 2nd phone number to try and see if i get a message, but to confirm that the new number is mine i need to enter a code of 6digits too, i didn't recieve it.
It's likely your mobile phone provider (who are you with?) - there's not much we can do about that unfortunately. We'll be looking into adding new types of 2FA authentication (instead of SMS) soon.
