Can't log in to web portal

I just recently installed the Avast Mobile Security app and its Anti-Theft component on my android phone. In “Settings” of the app I selected “avast! Account” and attempted to create an online Avast account. However in your app I was only asked for my email address while I was creating an Avast account, but I wasn’t asked for a password which I thought was strange. I filled in my email address nonetheless and afterwards saw under “avast! Account” in the app that my email address had been successfully connected to a new Avast account.

I then went to your web portal at my.avast.com to attempt to log in to my new account. However I had no idea what password to use since your app never asked me to create one, so I wasn’t able to log in. So I clicked “Forgot your password” to reset my password, hoping that this would eventually enable me to log in. I did this several times but I still haven’t received any email to reset my password.

I would like to be able to log in to your web portal with the email address that I used to create an Avast account in your app. Thanks if you can help.
