Space comes with a built-in authenticaton module that lets users log in with Space username and password. In addition to that, you can enable LDAP and third-party account authentication by configuring and enabling additional Auth modules.
Built-in authentication module
The Built-in Auth Module is the native authorization scheme for managing user account credentials. It is enabled by default.
Third-party authentication modules
These authentication modules allow the users to log in with third-party account credentials.
Open LDAP and Active Directory authentication modules
Logging in with multiple credentials
Depending on the auth modules enabled and their configuration, it may be possible for a user to log in with different credentials, all of which will be tied to a single username.
A list of credentials which the member has ever logged in with is shown in the member profile under Logins.
Detach credentials from a user account
Unwanted credentials can be removed from the user account. For exemple, if the user has mistakenly logged in with their home Google credentials instead of the work one, the wrong credentials can be detached from their username:
Open the user profile.
On the left-hand sidebar, choose Logins.
Locate the wrong credentials on the list and click Detach.
If built-in module credentials were detached by mistake, access can be restored by resetting password on the login form.
