User reviews

Users appreciate that the 2FAS Auth extension supports multiple platforms and makes using two-factor authentication less tedious and more secure. However, many find it inconvenient because it relies heavily on the phone to approve codes, with frequent issues around delayed or missing push notifications. The extension cannot function independently without the mobile app and requires a complex setup process. Some users would prefer an extension that generates or autofills codes directly rather than requiring manual approval and input.
Pros
  • Works as advertised to facilitate two-factor authentication without compromising security.
  • Cross-platform support including iOS and Android devices.
  • Simplifies the process of entering 2FA codes compared to manually typing them.
  • Open source and supports backup and export of tokens.
  • Provides a less tedious 2FA experience compared to other apps.
Cons
  • Requires constant use of the phone to approve 2FA codes, reducing convenience.
  • Push notifications to phone often do not arrive or are delayed.
  • The extension only acts as a companion to the mobile app and cannot generate codes independently.
  • Setup and pairing process is complicated and sometimes does not work as intended.
  • Does not autofill 2FA codes automatically; requires manual triggering.

I have received notification browser extension data error.
by David C, 2025-05-03

Setup was straight forward and works as advertised, making the 2 factor authentication just a bit less tedious without compromising security. Btw: the whole point of 2 factor authentication is that you need your phone to log into an account, so that it is not enough when someone only has access to your username and password. So the issue most negative reviews cite here is actually the feature of 2 factor authentication! Please don't compromise your security by having both the password and the 2 factor codes on one device out of convenience!
