Verified usage

Verified import paths — ran on the pinned version, not inferred.

Yubico

✓ from yubico_client import Yubico

Standard import path since 1.0.

Verify a YubiKey OTP using the Yubico validation API.

import os from yubico_client import Yubico client_id = os.environ.get('YUBICO_CLIENT_ID', '') secret_key = os.environ.get('YUBICO_SECRET_KEY', '') yubi = Yubico(client_id, secret_key) otp = 'ccccccbcvghfvbjfbbgvhu' # example OTP if yubi.verify(otp): print('OTP is valid') else: print('OTP verification failed')

Debug

Known issues

breakingIn version 1.0, the import changed: 'import yubico' no longer works; use 'from yubico_client import Yubico'.

fix

Update imports to 'from yubico_client import Yubico'.

affects: >=1.0

gotchaThe library uses the Yubico validation API v2. You must have a client ID and secret key from Yubico. Without them, verify() will raise an exception.

fix

Set environment variables YUBICO_CLIENT_ID and YUBICO_SECRET_KEY.

affects: all

gotchaverify() returns True/False, not a Yubico response object. For detailed failure reasons, catch exceptions from yubico_client.errors.

fix

Use try/except around verify() to get exceptions like YubicoVerificationError.

affects: all

Errors

Common errors & fixes

ImportError: No module named yubico_client

Installed old 'yubico' package or forgot to install yubico-client.

fix

Run 'pip install yubico-client' and use 'from yubico_client import Yubico'.

AttributeError: module 'yubico_client' has no attribute 'Yubico'

Used old import 'import yubico' instead of 'from yubico_client import Yubico'.

fix

Change import to 'from yubico_client import Yubico'.

yubico_client.errors.YubicoVerificationError: No such client

Invalid client ID or secret key, or missing environment variables.

yubico_client.errors.YubicoVerificationError: Bad OTP
