The multi factor authentication code sent by email when logging in for the first time on a new device?

What happens if I don’t have access to my registered email? : You’ll need access to your registered email to reset your password and complete verification when signing in. If you can’t access it, contact our Care team and we’ll help you get back into your account.
To contact 48 support see the links in my signature below.
By the way, it's not a great idea to post personal information such as your phone number in a public forum like this where anybody can see and use it.
You might want to edit your post to remove your phone number.
