SpookyOTP
Lightweight Python package for TOTP/HOTP (Google Authenticator) codes
Description
This is a lightweight package for generating TOTP and HOTP codes used for two-factor authentication. They can be used with Google Authenticator or FreeOTP.
Some features (such as using different hashing algorithms or displaying more than 6 digits) do not work with Google Authenticator.
URIs generated (and QR codes encoding them) follow the Google Authenticator format
Example
from spookyotp import (get_random_secret, TOTP, from_uri)
secret = get_random_secret(n_bytes=10)
totp = TOTP(secret, 'Example', 'user@example.org')
totp.save_qr_code('qr.png')
# you can now load the QR code with your app of choice
code = input("Enter code: ") # or raw_input in Python 2
matches = totp.compare(code)
if matches:
print("Correct!")
else:
print("Incorrect.")
# serialization and deserialization is supported via URI
uri = totp.get_uri()
new_totp = from_uri(uri)
Why Spooky?
I created the git repo on Halloween, and there is already a project called PyOTP.
