SSO (Single Sign On)
Single Sign-On (SSO) is an authentication mechanism that allows users to access several applications with only one set of login credentials.
By enabling SSO for your Annoto widget, you become responsible for the authentication of your users: they get authenticated through your own login portal and can use Annoto services freely.
- 1.An unauthenticated user requests access to your site (post login details to your server).
- 2.Your server authenticates the user, The user gets authenticated using your own authentication and authorization process.
- 3.If the user access is granted, You create a secured JWT payload that contains information about the user, using any standard library.
- 4.The JWT token should be part of the login post answer (or some other query as you see fit).
Annoto will not save the user login session. The
annotoAPI.auth(token)should be called at each page load.
What you will get from Annoto:
- Your clientID
- A unique secret that will be used to sign JWT tokens.
THE SECRET MUST BE KEPT CONFIDENTIAL ON YOUR SERVERS.
JWT payload should contain the required user information, and be encoded (signed) using the provided SECRET.
The JWT token MUST be signed using HS256 algorithm.
The JWT payload should contain:
If email is not provided, email notifications for users won’t work.
There are libraries available for virtually any programming language.
