I'd go with number 2 unless you want to buy everyone a hardware token (option number 3). There are open source solutions (I've used https://2fas.com/ ) and very common solutions (Google Authenticator). You can even print out the QR code and put it in a secure location (safe, safe deposit box) as a break-glass in case everyone's phones cease functioning. - Source: Hacker News / almost 2 years ago

2FAS is a very solid MFA; Bitwarden is designed to be a password manager, so I wouldn't suggest using it as a 2fa. Keep it separate imho. Source: over 2 years ago

I advise you to combine any password manager you chose with a 2-Factor Authentication app, I use 2FAS, but many prefer Aegis Authenticator. Both are good, there are many others too - but most people I've heard complain about Google Authenticator, so o stay away from it lol. Source: over 3 years ago

The public opinion surrounding 2FAS, a two-factor authentication (2FA) app, demonstrates a generally positive reception, highlighting its utility and distinct advantages in the competitive security and privacy domain. As an open-source and feature-rich authenticator, 2FAS has carved out a respected place alongside other notable players such as Authy, Google Authenticator, and Aegis Authenticator.
Ease of Use and Functionality: Users frequently commend 2FAS for its simple yet fully functional design. The app facilitates the addition of online accounts via manual entry or QR codes, supporting both Android and iOS platforms. The ability to perform encrypted cloud backups โ in iCloud for Apple devices and Google Drive for Androids โ is particularly valued, ensuring users can recover their authenticator data if devices are lost or upgraded. By not requiring a phone number or account registration, 2FAS mitigates risks associated with SIM-swapping fraud.
Security and Privacy: Security-conscious users appreciate that 2FAS provides encryption for backups and does not default to unencrypted syncs unlike some competing solutions. Its open-source nature means the community can scrutinize and improve its security protocols, further enhancing trust among users. The app supports PIN access and integrates device-specific biometric authentication like FaceID or TouchID on iOS devices, adding layers of security and convenience.
Cross-Platform and Integration Capabilities: The app supports cross-platform functionalities, which are frequently hailed by users, including browser extensions that enable seamless OTP auto-filling on web forms. This integration reduces friction during authentication processes, which many find favorable when compared to other authenticator apps.
Independence from Big Tech: Many users appreciate the independence of 2FAS from larger technology companies, which often brings concerns over data privacy and vendor lock-in. This aligns well with users who express distrust in proprietary systems that are less transparent about data handling and security practices.
Community Feedback: Across various discussion platforms, 2FAS receives recommendations for its straightforward interface, strong security posture, and robust backup features. Users often switch to 2FAS following disappointing experiences with other two-factor authentication solutions, particularly those associated with issues like slow performance or lack of critical features like end-to-end encryption.
Migration and Backup Solutions: The ability to export and import OTP information easily is frequently mentioned as a vital feature, especially useful for users switching devices or transitioning between mobile operating systems. The option for hosting encrypted backups in personal cloud locations provides a safety net against device loss without compromising security.
While 2FAS has received numerous accolades, it appears that some users observe minor limitations, such as the absence of an Apple Watch app. Although not a critical flaw for many, expanding its ecosystem to wearable tech could enhance its appeal to users seeking comprehensive cross-device functionality.
Overall, 2FAS garners a largely positive public opinion, with users citing its security, privacy, and user-friendly design as standout features. As the software landscape evolves, continuing to address user feedback will be crucial in maintaining its competitive edge in the two-factor authentication market.
