+description: >
+    Implement to provide user password set functionality. Since this
+    needs an authenticated session, there is no need of old password.
+    User ID is part of the dbus object.
+methods:
+    - name: SetPassword
+      description: >
+          Set the user password. If the user already had a password, it will
+          be updated, else sets the password.
+
+          InsufficientPermission error doing so would mean that, the caller
+          does not have required permission to update the password.
+
+          InternalFailure error would mean that, caller had required
+          permissions, but, there was a software error.
+          Errorlog metadata would need to be looked into when this happens.
+          Re-try once on this error and if that fails, do not try anymore.
