+## Migrate Authentication
+
+There are two possible ways to migrate user accounts to a different authentication backend.  
+I have personally used the first option, but the second option might work as well
+
+### Option one: Match Jellyfin Username
+
+The first option is simply matching the Jellyfin username to the username, UID or other provided by the authentication backend.  
+After setting the username, simply switching the authentication provider allowed logging in with the new authentication backend.
+
+### Option two: Copy Progress from library.db
+
+For the second option, a new user account is created.  
+The progress of the old user account will be copied to this newly created account.
+
+A guide for the process can be found on Reddit.
