Issues Accessing Account

Hello, I was working on a project for a client, I created an account for them and transferred a project from my account to this new one. They logged in, added a site plan, and I tried to log in after in order to finish & publish the site. I have been getting errors since and havent been able to log in
I emailed support but no reply yet, can anyone help

That is not something community members would be able to do. You have a username or credential problem if you are trying to login as the client. In the near future you would want to be on a freelancer plan or ^ and have the client add access for your account.
