TFACGUI

Web-based variant

TFAC GUI is a 2FA (Two-Factor Authentication) token generator GUI.

It currently supports the following setups:

• TOTP
  • Hashing algorithm
    • SHA-1 (default)
    • SHA-256
    • SHA-512
  • Token generation interval
    • 30 seconds (default)
    • Any amount of seconds between 1 and 60
  • Token length
    • 6 digits
    • Any amount of digits between 1 and 10
  • Custom labelling of TOTP config entries (can be changed retro-actively)
• Import / export of (encrypted) backups of the 2FA key chain

30 seconds with SHA-1 is the de-facto standard for most implementations of 2FA (Google Auth even ignores most of the parameters when set differently)

It's a spiritual successor to TFAC GUI, which is essentially the same thing that I wrote in C some time ago, but way, waaay more lightweight and much less portable compared to this. This here only carries its name as a legacy, because it no longer uses the previously utilized C-library TFAC that was powering the native TFAC GUI.

This 2FA GUI is written using Blazor WebAssembly and functions 100% statically, zero-knowledge and client-side only.

It has a .webmanifest file that makes it installable as a PWA on smartphones and computers.

User data is stored in localStorage but can be purged with a button click, and is only ever exported out of the app's context via the export functionality, which requires you to encrypt the exported data with a password.

Hope you enjoy, cheers :D
