Log in to Moodle using one time user key.
Auth plugin for organising simple one way SSO(single sign on) between moodle and your external web application. The main idea is to make a web call to moodle and provide one of the possible matching fields to find required user and generate one time login URL. A user can be redirected to this URL to be log in to Moodle without typing username and password.
The plugin supports user provisioning.

Thanks Dmitrii for sharing this plugin with the community. I was able to successfully test the functionality (with a small usability issue detected - redirecting after the sign in - which I reported to your tracker). The design and implementation if clean and easy to follow and understand. I like the interface
userkey_manager_interfaceallowing for alternative implementation of the actual keys generation and storage in the future.You are cleared to land now, welcome to the Plugins directory!
You can use this code https://github.com/moodlehq/sample-ws-clients to build your test client. Also don't forget to configure your moodle to work with web services and configure auth_userkey plugin using this doc https://github.com/catalyst/moodle-auth_userkey/blob/master/README.md
Please let me know if you have any questions.
It usually depends on what sort of integration are you after. This plugin is ideally for organising SSO with your application and moodle.
Very simple scenario:
1. Install and configure auth_userkey plugin for your moodle.
2. Create a script in your web application to interact with moodle auth_userkey plugin to generate login key for users and redirect them to moodle.
3. Put some link in your web application to let users to click on it and execute the script from step 2.
4. Profit.
Look at documentation to find some PHP code examples for testing https://github.com/catalyst/moodle-auth_userkey/blob/master/README.md
Your requirements are very open ended, and there are many out of the box solutions, ie SAML, CAS, Auth2 etc which could make the integration easier. This plugin may or may not be the best solution.

the plugin page says that this plugin is compatible with Moodle 3.3 - but as the comment on GIT hub
https://github.com/catalyst/moodle-auth_userkey/issues/15#issuecomment-306955454
points out, its currently not working with 3.3. The version info on this page should be corrected to save users some hassle.
Stack trace: •line 513 of \cache\classes\definition.php: coding_exception thrown

can any one help??
It's really hard to say what is broken based on your description as trace you attached is related to some errors in cache class. If you do believe that this error is triggered by auth_userkey plugin please feel free to create an issue in https://github.com/catalyst/moodle-auth_userkey Please provide more details for us to replicate it (Moodle version, any specific settings and etc)
Also, have you tried to install other plugins? Maybe it's a just general error you are getting for any plugin?
Thanks,
Dmitrii
could you give me an example of how to call from external application ?, as I'm using asp.net application
That's correct, users who have this auth method set can't login directly to moodle.
Unfortunately I'm not able to provide any .NET examples. You can find a PHP example in the plugin docs https://github.com/catalyst/moodle-auth_userkey/blob/master/README.md
Cheers,
Dmitrii
