bna 4.0

Battle.net Authenticator routines in Python.

Using the command-line tool

bna is a command line interface to the python-bna library. It can store and manage multiple authenticators, as well as create new ones.

Two things to remember:

• Using an authenticator on the same computer as the one you’re playing on is not secure.

• It is impossible (without knowing the secret) to import an existing authenticator

Configuration is stored in ~/.config/bna/bna.conf. You can pass a different config directory with –config=~/.bna.conf for example.

Creating a new authenticator

$ bna --new

If you do not already have an authenticator, it will be set as default. You can pass –set-default otherwise.

Getting an authentication token

$ bna
01234567
$ bna EU-1234-1234-1234
76543210

Getting a serial’s restore code

$ bna --restore-code
Z45Q9CVXRR
$ bna --restore EU-1234-1234-1234 ABCDE98765
Restored serial EU-1234-1234-1234

Using the python-bna library

Requesting a new authenticator

import bna
try:
        # region is EU or US
        # note that EU authenticators are valid in the US, and vice versa
        serial, secret = bna.request_new_serial("US")
except bna.HTTPError as e:
        print("Could not connect:", e)

Getting a token

# Get and print a token
token, time_remaining = bna.get_token(secret=secret)
print(token)

# print a new token every time the previous one expires
from time import sleep
while True:
        token, time_remaining = bna.get_token(secret=secret)
        print(token)
        sleep(time_remaining)
