acc

acc - Demo Authenticator from Command Line.

acc is a full featured two factor authenticator. It performs the same function as Google Authenticator but can be run from the command line. This is really useful for testing login that uses a two factor authentication system.

The only supported hash is SHA1 at the moment.

Look in the ./Makefile for how to run the program.

To build

$ go get
$ go build

To run

Save the image of a QR code that is presented or do a screen capture of the QR code to a file. Let's say that the QR code is saved to ~/Downloads/711210.png. Run the tool with the --import flag to bring that in.

$ ./acc --import ~/Downloads/711210.png

This should create or append to an existing acc.cfg.json file. It will also print out the name of the account that this authenticates for.

You should be able to list the accounts and realms that are in the config file with:

$ ./acc --list

To generate a 2FA token

Given that you have an account /app.example.com:demo5@gmail.com you can generate the next token for that account with:

$ ./acc --gen2fa "/app.example.com:demo5@gmail.com"

It will loop and show you how long you have left on the 2fa token.

The 2fa token is copied to the "clip board" so you should be able to paste it into some other application.
