-# redis-auth
 
-redis 第三方认证模块
+The Redis third-party authentication module has the following issues due to the fact that open-source Redis authentication reads authentication information from files:
+
+- From a security perspective, saving passwords in configuration files is not secure and cannot meet enterprise level security requirements.
+- When in cluster mode, the permission information in each instance is separate and it is not easy to maintain consistency.
+
+
+# Roadmap
+
+- [ ] Support synchronizing user permission information from the postgreSQL database.
+- [ ] Support synchronizing permission information from HTTP requests.
+
+
+# Link
