+
+---
+
+`401` is a client error while `403` is a server error.
+
+---
+
+`401` means the resource was permanently moved while `403` means it was temporarily moved.
+
+#### --answer--
+
+`401` means credentials are required while `403` means the client has valid credentials but lacks permission for the resource.
