Warning to change ARI username/pwd

total newbie to fpbx. I got an automated emal from my fPBX the other day
SECURITY NOTICE:

Action Required : Change ARI Username/Password:
Your system is using default ARI username so recommend you to please change
ARI username and password at the earliest (If ARI is not visible, Please
enable ‘Display Readonly Settings’ And 'Override Readonly Settings

so I did that but found that there are no users in the Asterisk Rest Interface.

should I still create one?

Howdy! Welcome to the forums.

What version of FreePBX are you using ?

This has been like that since 2023.

Go to Settings > Advance Settings
Set Display Readonly Settings & Override Readonly Settings to YES and submit.
Then, search “ARI Username” on that page and change both, user and password to whatever you want.
