Hello I am unable to sign in to a lab Entra ID tenant (xxxxxxxxxxxxx.onmicrosoft.com) and I am the only global admin of that tenant (basically after I had to reset my phone none of the Authenticator codes are avaliable for me to sign in with that account)

    Hello @Gareth Smith,

    The issue relates to a tenant lockout situation where no other global admin in the tenant has the necessary admin rights to re-register MFA.

    To resolve this, we engaged our Data Protection team through a support ticket. Please connect with our support team via the ticket, and they will assist you in resolving the issue.

    I hope this information is helpful. Please feel free to reach out if you have any further questions.
