Hi Sharon Yuvitza Jirsa Gonzalez,
Thank you for reaching out to Microsoft Community Support and I apologized for any inconveniences cause by this issue.
May I know if you are still able to sign in to your account using any alternative methods? (Phone or SMS)
- If yes: you could access to this link: https://mysignins.microsoft.com/security-info to delete old Authenticator (if you had) and then register for new MFA on Microsoft Authenticator again.
- If no: please contact your local office's IT team and ask them to access Entra Admin Center with Global Administrator and ask them to follow this article: https://learn.microsoft.com/en-us/entra/identity/authentication/howto-mfa-userdevicesettings. They will be able to reset your multi-factor authentication (MFA), allowing you to re-register Microsoft Authenticator.
Unfortunately, there are no other alternative ways to access to your account if you are being locked out due to Microsoft Authenticator and you do not have any other verification methods. Only your organization's administrator could help you with this.
