User reviews

Users appreciate 2FAS Auth for its security, cross-platform support, and straightforward setup. It integrates well across devices and is considered a strong alternative to other 2FA solutions. However, common issues include unreliable push notifications, mandatory mobile phone approval for every authentication, and inability to generate or autofill codes directly via the extension. Several users express frustration with the dependence on the mobile app and delayed or failed notifications, making the experience less convenient. Despite this, many consider it a reliable and secure tool, with some wishing for enhanced desktop features.
Pros
  • Secure and smooth integration across multiple devices.
  • Works cross-platform on iOS and Android, supporting local network backup and token export/import.
  • Easy to set up and functions as advertised, maintaining security without complexity.
  • Open source with code that can be audited for security.
  • Effective replacement for other 2FA apps like Authy, with good backup and export features.
Cons
  • Frequently fails to send push notifications to the phone, causing delays or no response.
  • Requires linking and approving on a mobile phone every time, which users find inconvenient.
  • Extension does not generate or autofill codes directly; it depends on the mobile app for code approval, leading some users to find it redundant.
  • Onboarding and pairing process can be complex and sometimes does not work properly.
  • Lack of desktop-only usage; mobile phone is always required, limiting usability.
