if you feel enabling the
enable_insecure_login option is too insecure ... then there is an app for exactly this use case.
It enables Splunk to display dashboards without the need to provide a username nor a password.
Here is the link to this app https://splunkbase.splunk.com/app/4377/
Hope this helps ...
@daniel333 You can pass the username and password in dashboard URL so it will not prompt you for login, for example. See the post https://answers.splunk.com/answers/622600/how-to-pass-username-and-password-as-a-parameter-v.html
