How do I sign back in to my work account via the authenticator app when the app requires me to use the app as a two step verification method?

If you are signed out of your work account and the Microsoft Authenticator app is asking for a verification code that you cannot access, you may need to follow these steps:

1. Contact your IT department or administrator: Since you are unable to access the authenticator app due to being signed out, your IT department may be able to reset your multifactor authentication (MFA) settings or provide an alternative method for verification.
2. Use a backup method: If you have set up any backup verification methods (like a phone number or email), you can use those to regain access to your account.
3. Re-register MFA: If your organization allows it, you might need to re-register for MFA. This typically involves having an administrator set the requirement for you to re-register.
4. Access the security settings: If you can access your security settings through a web browser, you may be able to manage your sign-in methods there. You can view and delete existing sign-in methods if necessary, which might allow you to set up the authenticator app again.

Unfortunately, without access to another device or the authenticator app, your options are limited, and reaching out to your organization's support team is likely the best course of action.
