Adobe reader

The built-in Mac Preview app is a good alternative in most cases.

If your Mac is currently set to automatically open Adobe Reader, open a Finder window, select (highlight) any PDF file and then press command I (or use Finder File menu Get Info) and in the Open With section of the Information window change the application to Preview and then click Change All.

No idea what you mean. You should never have to put in a code or password for the free Reader. And I have to ask, who is "they"?

Are you getting the Reader DC directly from Adobe?

Are you opening the document on your mac or your phone?

I had a similar problem on my mac. Delete adobe reader. ... should now use preview, I'd think. ... two weeks later, I

Re-installed. Should not have to wait two weeks. I assume I updated to the lastet version.

fyi: adobe had a bug in the mac version. I ran across about a month ago. Adobe got confused thinking the document was password protected. whatever, it was asking me for a password. Said I had to sign up for an adobe account which I didn't do.
