Microsoft Authenticator is an MFA app for securing online accounts. Launched in 2016 as a TOTP generator, the app has now evolved into an authentication solution for Microsoft 365 and Entra ID environments as well as other major third-party apps. Users can quickly verify their identities in supported apps and services by approving the push notifications sent to the Microsoft Authenticator app.
Microsoft Authenticator also supports all apps and services that use TOTP-based authentication. After registering with the application once, the Microsoft Authenticator app will continuously generate codes that can be used to log in toaccounts without a password.
Traditional passwords come with a host of disadvantages, from being easily forgotten to being vulnerable to hacking. Weak or reused passwords can compromise security, while even strong passwords can be susceptible to sophisticated cyberattacks. To address these issues, MFAis widely used as a secure alternative to password-based authentication. Authenticator apps play a crucial role by providing multiple layers of verification, ensuring that even if one factor is compromised,access to accounts is still protected.
Microsoft Authenticator supports MFA for a large suite of applications and services with TOTP-based authentication. However, its mainadvantage over other authenticator apps is its tight integration with Microsoft's solutions, the most prominent being Entra ID. Entra ID is a widely used IAM solution andthe preferred choice for building a cloud-based directory.Using Microsoft Authenticator for passwordless authentication for Entra ID keeps organizations safe against cyberattacks and phishing attempts by a large margin, at no additional cost.
