Hello Larry,
Thank you for your swift support.
It was indeed all explained in your book. I was simply not taking it in the correct order. My bad.
After changing the password, my Terminal showed this message: Warning: Since password will be sent to server in plain text, use ssl connection to ensure password safety.
How can I check if my Internet provider gives me a SSL connection?
Now, this shows that actually I don't understand what is MAMP (or XAMPP). So I'm going to ask a series of questions that will probably look stupid to you (sorry about that):
What happens for example, when I place files in the htdocs folder?
Does it "stay" on my computer or is it "sent" over the Internet? I don't understand what is the risk?
When I am going to create a web site, am I going to create and manage my database directly on the space provided by a web-hosting provider through phpMyAdmin or will I do this first on MAMP and then upload it on the server?
