Acrobat READER DC, asking for login

[RedStir]

When I open a document with Acrobat READER DC, I am prompted to sign in using some credentials.  The options are to use my Google account or some other. 

I have never seen this before, and after a new installation on a machine, replacing Acrobat Reader XI (also free product), I am presented with this.

How do you make it stop without having to sign in??

Sorry to read this,

have you created a free account with Adobe, no cost attached, no purchase needed?
