Hi thanks for reaching out, I'm Arlene an Independent Advisor.
Can you still access the email address where the code is being sent?
If not, try selecting “I didn’t get a code” or “Use a different option” on the sign-in page. If you can't access that email at all, go to https://account.live.com/acsr to recover your account. Make sure to check your spam or junk folder just in case the code was filtered there.
Hope it helps. Please let me know for further assistance.
Regards,
Arlene D.
