Your account has been configured to use Multi-Factor Authentication.

When you sign on, you will continue to use the same username and password. Before your verification is complete, you will receive a notification asking you to launch the Azure Authenticator mobile app and press the Authenticate button to complete your sign on. If you don't confirm the sign on by pressing Authenticate, the sign on will be denied.

You should only press the Authenticate button when you receive the Azure Authenticator mobile app notification if you are actually signing on to the application. Otherwise, someone may be trying to sign on with your username and password and you should report this potential fraud to your IT administrator.
