The platform automates most of the hosting and management of your sites for you. You don’t need to worry about things like security, backups, updates, or performance.
Once DNS is resolved, you will be able to log in directly from the platform without the need for credentials on the website login page.
Or you can log in from the 'Manage Website' (gear icon) section:
Each website is set up with an Admin username that is randomly chosen.
Do not make any changes to or delete this user as it will affect the ability of the platform to interact with the site.
If you want to give someone else access to log in directly to the site, create a new user in WordPress and direct them to the /admin or /login.php pages of the site to log in.
