    Hello Joseph,

    This looks like a MFA error code. You will want to reach out to your IT Administrators to have them Require you to re-register your Multi-Factor Authentication options.

    If this is helpful please accept answer.

    @Joseph, Josmi

    Looks like you are getting error due to MFA.

    Error Code: 500121
    This typically occurs when authentication failed as part of the multi-factor authentication (MFA) request, it may indicate a configuration or service error. To resolve this issue, can you try resetting (require re-register) MFA for your user.

    User's image

    With this user will be asked to re-register for MFA. Once the registration is done for user, you can again try to login and it should be successful.

    Note: You will have to use global admin account to login to Azure portal and select the option "require re-register MFA".

    Let me know if you have any further questions on this.
