Good afternoon,
I am the administrator of the Power BI account for my company. I’ve lost access to my Microsoft Authenticator app and can no longer log into my account. I still know my password, but I’m unable to complete the second authentication step through the Authenticator app.
My personal email is registered as the administrator contact for Power BI account, and I am able to receive codes to reset my password. However, when I try to sign in, the system only offers the option to approve the login through the Authenticator app.
Thank you for your assistance.

If you are a security administrator, this can be reset in the Entra ID portal under Users, your username, and authentication methods
