WordPress Access with Maestro
What level of access will I get to manage the WordPress site?
Once the client has granted access to the Bluehost account, you will have access to all the sites which are hosted in that hosting account, the WordPress Admin of all the sites, and the cPanel of the hosting account. You will not be able to access the marketplace, email, domains, account center, cart and the billing/credit card details of the account.
You will be given a WordPress Administrator role once the site owner accepts your request. With this access, you can add, delete, and modify content, download, activate, and modify plugins and themes, and perform upgrades and updates. Basically, you will be able to perform all the tasks that you require for development, design, and maintenance of a WordPress website.
You can find the entire list of privileges a WordPress Administrator gets on this official WordPress page.
