Hello. If you are using the hosting that you received along with WebSite X5, then go here https://hosting.websitex5.com/panel/ and in the E-mail section you will find the data you need. Provided that you have connected your domain.

It is not a good idea to show passwords on a public forum.

As soon you get access to your account, you should change the password - and elsewhere you eventually use the same password.
