This uses django-agent-trust to add OTP-based machine authorization to django-otp.
See django-otp for more information on the OTP framework.
This version is supported on Python 2.6, 2.7, 3.2, 3.3, and 3.4; and Django >= 1.4.
This is technically a Django app, but only for testing purposes. To use this project, just make sure you have django-otp and django-agent-trust installed correctly.
This package provides subclasses of OTPAuthenticationForm and OTPTokenForm with an extra boolean field called otp_trust_agent. The user can check this option to indicate that they’d like to bypass OTP verification when accessing the site from the same browser in the future.
When these forms are used with django.contrib.auth.views.login(), we will call the appropriate django-agent-trust APIs automatically. If the trust option is selected, the agent will be trusted persistently; if not, it will be trusted for the current session. Views willing to accept a trusted agent in lieu of OTP verification may then use trusted_agent_required() in place of otp_required().
Extends OTPAuthenticationForm with support for agent trust.
If you use any OTP-aware authentication forms that are not trusted-agent-aware, then the following decorator may be useful. For example, suppose you have one view protected by otp_required() and another that is protected by trusted_agent_required(). If an authenticated user visits the first view, he will be asked to provide an OTP token via the standard OTPTokenForm, which will verify the user, but will not set up a trusted agent. If he then visits the second view, he will be asked to verify again, this time with the trusted-agent-aware OTPTokenForm. This is clearly not what you intend, since OTP verification should be more than sufficient to authorize the user for the second view.
To get around this, the following decorator effectively merges otp_required() and trusted_agent_required() into a single decorator that will be satisfied with either a verified user or a trusted agent. The default behavior is to act exactly like otp_required(); pass accept_trusted_agent=True to enable the more lenient policy.
Similar to otp_required(), but with an extra argument.
|Parameters:||accept_trusted_agent (bool) – If True, we’ll accept a trusted agent in lieu of OTP verification. Default is False.|
