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
OTP from Mobile
$ bna --otpauth-url otpauth://totp/Battle.net:EU123412341234:?secret=ASFAS75ASDF75889G9AD7S69AS7697AS&issuer=Battle.net&digits=8
Now paste this to your OTP app, or convert to QRCode and scan, or manually enter the secret.
Note: This will not work with "Google Authenticator" as it does not support 8 digits, try "FreeOTP"
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)
