+```ini
+[common]
+;plugin listen ip
+plugin_addr = 127.0.0.1
+;plugin listen port
+plugin_port = 7200
+;user and passwd for basic auth protect
+admin_user  = admin
+admin_pwd   = admin
+
+[users]
+;user1
+user1 = 123
+;user2
+user2 = abc
+
+[disabled]
+;user2 is disable
+user2 = disable
+```
+
+   One user each line. Username and token are split by `=`.
+
+2. Run frps-multiuser:
+
+   `./frps-multiuser -c ./frps-multiuser.ini`
+
+3. Register plugin in frps.
+
+```ini
+# frps.ini
+[common]
+bind_port = 7000
+
+[plugin.multiuser]
+addr = 127.0.0.1:7200
+path = /handler
+ops = Login,NewWorkConn,NewUserConn,NewProxy,Ping
+```
+
+4. Specify username and meta_token in frpc configure file.

+   For user1:
+
+```ini
+# frpc.ini
+[common]
+server_addr = x.x.x.x
+server_port = 7000
+user = user1
+meta_token = 123
+
+[ssh]
+type = tcp
+local_port = 22
+remote_port = 6000
+```
+
+   For user2:(user2 can't connect to server,because it is disable)
+
+```ini
+# frpc.ini
+[common]
+server_addr = x.x.x.x
+server_port = 7000
