If you opt for just maintenance without hosting:
When you sign up to work with WebCare.Live, you will automatically receive a welcome email asking you to send us your login credentials (WordPress dashboard and hosting).
In that email, we provide you with access to a tool that allows you to hide your login credentials behind a self-destructing link that only our team can see.
If you choose to host your website(s) with us, you need not worry about that, we will log in from the server.
