Verification Code Email Issue

Question

Hello, how are you doing? when I try to log in my azure account I am asked to enter a verification code that is supposed to be previously emailed to my alternative email account. The issue is that this verification code was emailed once but when I entered it, the system refused it and I couldn't log in. Since then, the system keeps asking me for a verification code over and over but no email is sent to my alternative email account anymore, therefore I am not able to log in. As far as I know, the alternative email account is correct. Please, could you help me solve this issue?
