2FA made no longer annoying but enjoyable



During sync, you are NOT supposed to do any of the listed behaviors or you are totally responsible for your data loss:

  1. Moving, renaming, deleting or manually editting any file in our app folder (copying and pasting shall not cause issues though).
  2. operate account info between several devices in a REALLY frequent rate.
  3. use different encryption passwords among different devices.

You shall also note that if you connect an encrypted FoxAuth database to any sync service, ALL OTHER unecrypted FoxAuth databases on this service will be override.

Important Note

Please use Firefox Container, either the built-in feature or the extension, to manager your multiple accounts. FoxAuth may override your older accounts info when you try to input multiple accounts info without Container specified.


Here is how this project gets revisioning:

  • a - major changes, represents a complete overhaul of the code in the file, hardly distinguishable from before; you probably will never need to bump this; when creating new files just give it a version of 1.0.0.

  • b - mid-level changes, when you add or modify a significant chunk of code that alters the way the rest works; for instance when adding whole new features.

  • c - minor changes, such as most bugfixes; this is probably what you will be bumping most often.


We use encryption code from Firefox Send in WebCrypto API. Welcome as we are to any security review, it shall be more efficiently to perform it at that side.
