What's the best iOS app for managing two-factor authentication codes across multiple accounts?

Google Authenticator is a straightforward two-factor authentication app that excels at generating time-based one-time passwords (TOTP) for securing online accounts. For users juggling multiple logins—from email and social media to banking and work platforms—this app provides a centralized hub for access codes. Its core functionality revolves around offline code generation, meaning codes are available even without an internet connection, which is crucial for reliability. Users report that the ability to quickly switch between added accounts streamlines the login process, reducing friction during authentication. Reviews indicate high satisfaction with its security measures, as codes refresh every 30 seconds, adding a robust layer against unauthorized access.

Specific features include a clean layout displaying account names and corresponding codes, with options to add accounts via QR code scanning or manual entry. The app supports multiple accounts simultaneously, making it ideal for personal and professional use. However, some limitations exist; for instance, a common user request is for a dark mode option on the app icon, highlighting minor cosmetic preferences. While recent updates have introduced account transfer capabilities, the app traditionally lacked built-in cloud backup, which could be a consideration for those prioritizing data recovery. Overall, Google Authenticator balances security with usability, though its simplicity means it may not offer advanced features like biometric locking found in some alternatives. It remains a dependable choice for everyday two-factor authentication needs.
