+You can reset the password for the admin user using the CLI. The use case for this command is when you have lost the admin password.
 
 `grafana-cli admin reset-admin-password ...`
+
+If running the command returns this error:
+
+> Could not find config defaults, make sure homepath command line parameter is set or working directory is homepath
+
+then there are two flags that can be used to set homepath and the config file path.
+
+`grafana-cli admin reset-admin-password --homepath "/usr/share/grafana" newpass`
+
+If you have not lost the admin password then it is better to set in the Grafana UI. If you need to set the password in a script then the [Grafana API]({{< relref "http_api/user/#change-password" >}}) can be used. Here is an example with curl using basic auth:
+
+```
+curl -X PUT -H "Content-Type: application/json" -d '{
+  "oldPassword": "admin",
+  "newPassword": "newpass",
+  "confirmNew": "newpass"
+}' http://admin:admin@<your_grafana_host>:3000/api/user/password
