Authenticating using ORCID
ORCID uses the OAuth2 protocol for authentication and authorisation. This is a user centric authentication mechanism that allows users fine grained control over what third parties can and cannot do with their ORCID record. Actions that require user authorisation use the three-legged approach, as does authenticating users. It works like this:
- Your website directs the user to ORCID using a specially crafted request containing details of the permissions you would like the user to grant you. E.g. read or update
- The user authenticates to ORCID, if not already signed in
- The user grants (or denies!) permission to your application
- ORCID redirects the user back to your website with an authorization code
- You exchange the authorisation code for an access token using the ORCID OAuth API
- You include the access token in any subsequent requests you make
Implementing this in code is easier than it sounds.
More details can be found in the ORCID OAuth documentation.
