Microsoft Authenticator App - Basics
The Microsoft Authenticator app helps you sign-in to your accounts if you use two-factor authentication (2FA). Two-factor verification helps you access your accounts more securely.
|Two-factor verification (authentication)||A verification process that requires you to specifically use only two pieces of verification information, like a password and a PIN. This app supports both two-factor verification and passwordless sign-in.|
|Microsoft Account (MSA)||Your account associated with Microsoft products and cloud services like Outlook, OneDrive, Xbox LIVE, or Office 365. Your Microsoft account is created and stored in the Microsoft consumer identity account system that's run by Microsoft.|
|Work or school account||Your organization (EKU) creates your work or school account (such as @eku.edu or @mymail.eku.edu) to let you access internal and potentially restricted resources such as Office 365.|
|Verification Code||The six-digit code that appears in the authenticator app, under each added account. The verification code changes every 30 seconds preventing someone from using a code multiple times or shoulder surfing. This is also known as a one-time password (OTP).|
