 ## Details
 
+* Bugfix - Token request with Bearer returns error: [#4080](https://github.com/owncloud/android/issues/4080)
+
+   A new condition has been added into the network client to check if the network
+   request comes from TokenRequestRemoteOperation before setting the authorization
+   header. This allows users to have more than one logged-in account on the same
+   server.
