Authenticator App by 2Stable review
A feature-rich TOTP authenticator for Apple users who want autofill and sharing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Authenticator App by 2Stable generates time-based two-factor authentication codes for online accounts. It is designed for people using iPhone, iPad, Mac, Apple Watch, and supported browsers who want code generation alongside account organization, browser autofill, and sharing permissions. Accounts can be added by scanning QR codes, importing QR-code images or files, or entering secret keys manually. The app also supports offline code generation, biometric unlocking, widgets, and encrypted backup.
Its strongest fit is the Apple ecosystem. Optional iCloud synchronization keeps accounts aligned across Apple devices, while encrypted local storage and Face ID or Touch ID add access controls. The browser extension extends the workflow beyond the native apps, with support for Chrome, Firefox, Safari, Edge, Brave, Vivaldi, Opera, Tor Browser, and Waterfox. For households or teams that need controlled access to authenticator accounts, account groups and sharing permissions provide a more organized approach than a basic code list.
Migration is another notable strength. Authenticator App by 2Stable can import from Google Authenticator, password managers, and files, which may reduce manual account setup. The freemium model includes a free plan and in-app purchase options. Its main boundary is platform scope: automatic synchronization is built around Apple devices, and Android is currently presented as a waiting-list product rather than a live app. Choose it if you use Apple hardware and want browser autofill, imports, offline codes, and sharing in one authenticator. Users who need a live Android app should consider an alternative.
