I am watching your WP videos and new to WP but learning from your channel which is very helpful. I have registered a domain and hosting from your given link (Inmotion hosting) but yet I didn't get the user id and password. I did this on 2-09-2018. I made a call to the office for activation they had sent me details of AMP but WP Id or password I didn't get I would like to send you the email I have received from them. if you help me in sorting out this please let me know.
Seems like you didn't recieve the welcome email that had all of that info in it. You may need to have them give you the login to your AMP portal and also ask them to reset the WordPress login that was automatically installed for you.
