Ok, I will answer my own question.
The login to Piwik is at http://yoursite.com/piwik/ or wherever your piwik installation is. IF this shows no login prompt, but instead shows the installation prompt, that means that for one reason or another, your Piwik installation was not complete. You need to proceed with the installation again.
In my case, as soon as I got the javascript code 90% into the installation, I copied that and went on to install it on the blog pages, neglecting to press Next to finalize the installation.
That was why the http://mysite.com/piwik/ did not show a login but instead wanted me to install. Re-installation was relatively easy though although tedious.
Piwik would save new users a lot of grief if they would put a note like "You are not finished yet. You must click ""Next"" to finalize the installation" or something like that on the page where the javascript is displayed.
