Which iOS app should I use to manage two-factor authentication for multiple work accounts?

Microsoft Authenticator is a specialized tool designed to handle two-factor authentication (2FA) and multi-factor authentication across a wide array of services, particularly in enterprise environments. For users juggling several work accounts, such as Microsoft 365, Azure, or other SSO platforms, the app consolidates all verification prompts into a single hub. Its primary strength lies in simplifying the login flow; instead of manually entering codes, users often receive a push notification they can approve with a single tap. The app supports both time-based one-time passwords (TOTP) for standard accounts and number-matching for more secure approvals, a feature noted by users who prefer its two-digit prompts over traditional six-digit codes.

Specific features like cloud backup for account credentials and password autofill for saved Microsoft accounts add significant convenience. However, the setup process for non-Microsoft services can be less intuitive than some dedicated authenticator apps. User reviews also indicate occasional frustration with circular verification loops when other Microsoft apps are involved, a documented but persistent edge case. For corporate environments where IT mandates its use, Microsoft Authenticator provides reliable, ad-free functionality that integrates tightly with the Microsoft ecosystem, though migrating all accounts to a new device remains a commonly cited minor hassle.
