I’d reply to

> Is there a way to delete or change Login subtitle ? I am not sure what is the correct param name. I tried “login\_page.subtitle” OR “login\_page.sub\_title” but it doesnt work. I would like to change or get rid of this text, it will be confusing for our users. If you have forgotten your username or password, please ask your system administrator

but it’s closed. The documentation at [https://docs.search-guard.com/latest/kibana-login-customizing#customizing-the-login-page](https://docs.search-guard.com/latest/kibana-login-customizing#customizing-the-login-page) still does not mention the `message` value for `auth_domains`. The documentation has an example image which labels some text as “Subtitle”, but no such value is described in the text. (`searchguard.basicauth.login.subtitle` exists in Classic, so seems like the example image has not been updated to for the FLX documentation.)

@mikew Is this regarding FLX 1.6 as your other forum case? I’ll test that and get back to you with my findings.

Is it also about 1.6. I realised that version is EOL, but there the documentation for FLX is not version specific (where as for Classic there are version specific versions of the documentation), therefore I am assuming that the documentation for FLX is supposedly to be valid for all versions of FLX.
