Is there a good iOS app that provides strong two-factor authentication for safeguarding financial and government logins?

Authenticator · is a focused two-factor authentication (2FA) app for iOS that addresses the need for robust security on sensitive accounts, such as banking or government services. The app operates on the Time-based One-Time Password (TOTP) standard, allowing users to add multiple accounts by scanning QR codes or entering keys manually. Key features include encrypted local storage for codes, optional cloud backup to prevent data loss, and a straightforward interface that displays rotating six-digit passwords with countdown timers. For real-world scenarios, like securing a federal student loan portal, the app provides an additional layer beyond passwords, reducing the risk of unauthorized access. Reviews indicate that users appreciate the enhanced security, with one noting it alleviated stress over privacy concerns. However, some feedback points to imperfections, such as occasional confusion around subscription models and refund processes, which could be streamlined. The age rating has also sparked minor debate among younger users. Despite these quirks, Authenticator · delivers reliable performance for everyday 2FA needs, making it a practical tool for anyone prioritizing account safety without complex setups.
