Hi,

If you are using the "free" FamilySearch page

   https://www.familysearch.org/en/

Try a simple search. There are six fields for First, Last, birth location, birth year, death location and death year.

You should get the page titled:

  Historical documents we found for xx — FamilySearch.org

Navigate to the heading:

  Top people we found for xx in the shared Family Tree

The next line is the button:

  toggle this to learn about xx

Activate the button with the space bar, wait a few seconds and then look for:

  To view historical documents of xx sign in, or create an account.

Tab to the create free account link.

I sign in and every 2 weeks I have to manually sign in and check stay signed in for 2 weeks.
