+Title: Storing server configuration
+Slug: loginpath
+status: hidden
+
+
+When working with multiple servers, it is advisable to use the
+[`mysql_config_editor`](https://dev.mysql.com/doc/refman/5.7/en/mysql-config-editor.html)
+tool that ships with MySQL to store the authentication credentials in an encrypted file called
+`.mylogin.cnf`. Then, `mycli` can read and use those credentials.
+
+First, run the `mysql_config_editor` tool and enter the credentials:
+
+```
+$ mysql_config_editor set --login-path=my_server_alias --host=my.host.address --user=myusername --password
+Enter password: *****
+```
+
+Then, provide the `--login-path` option when running `mycli`:
+
+```
+$ mycli --login-path my_server_alias my_database_name
+```
