There are three ways to log in to ClickHelp:
All methods are available for both user types - Contributor and Power Readers.
Native ClickHelp credentials
This is the default authentication option, and it doesn't require any additional setup. When the user is created in ClickHelp, an email containing the credentials is sent to the email address specified during account creation. Users can change their passwords later in the User Profile. Also, ClickHelp administrators can reset users' passwords in their profile settings. You can still use this authentication method even if the SSO is enabled on your ClickHelp portal.
SSO
If your company uses SSO (such as Microsoft, Google, or Okta) to authenticate across different tools, you can use the same approach to log in to ClickHelp. ClickHelp supports the OpenID Connect technology of single sign-on. You can read more about configuring SSO in ClickHelp here: Single Sign-On (SSO). If needed, you can configure several SSO connections, for example, for different types of users - Contributors and Power Readers.
Login Tokens
The login token mechanism implies that you use links to ClickHelp documentation in your site or application, and your users won't need to manually log in. When a user clicks a link in your application, a login token is generated for that user (using the API Get Login Token method), the token is appended to the link as a parameter, and the user is authenticated behind the scenes. This means they don’t have to manually submit their ClickHelp credentials, but they need to log in to your site/application. Details about this approach can be found here: The Token Login Mechanism
