You can delete the admin account:
go to site/accounts/ and delete admin.php
go to your panel and you will be prompted to create your account!
If you want to run several instances of Kirby, you will need to create an account for each. If you set the same password you’ll just have one to remember but it’ll still be separate accounts for each site. Does that make sense?
Thanks for buying my theme and don’t hesitate if you have any questions!
There’s an upgrade for the theme coming in early this week as I’ve been made aware of a potential bug by a user. I’ll send you a message with instructions on how to install the update!
