Pros and Cons of Using Microsoft Authenticator

Pros:

•  It enhances security, especially for unregistered devices. It reduces the risk of unauthorized access and data breaches, which can be costly in terms of both financial and reputational damage

•  It simplifies the login process. There is no need to remember or type a password, which can be easily forgotten or compromised. Users can simply scan a QR code or enter a setup code to add an account, and then choose to receive one-time passcodes or push notifications on their phone

•  It works offline. Users can still approve requests or generate one-time passcodes even without cell or wireless coverage, as the app stores the OTPs on the device and does not rely on Microsoft's servers.

Cons:

•  It requires a compatible smartphone. Users need to have an Android, iOS, or Windows Phone device that can run the app and receive notifications. Users who do not have such a device or are not comfortable using it may not be able to use the app

•  It may not work with some services or apps. Users may need to authenticate to a wide range of services, apps, or websites that do not support Microsoft Authenticator or 2FA in general. In that case, users may need to use alternative methods, such as passwords, app passwords, or security keys

•  It may cause inconvenience or frustration. Users may encounter issues such as losing their phone, forgetting their PIN, changing their phone number, or receiving unwanted notifications. These issues may require users to reset their account, contact support, or disable the app
