We chose 'log in' for our more technical (vs. consumer) audience, but I
agree that going with the standard that your particular users might see
(~80% makes a 'standard') is the way to go.

On the one word vs two word question: English language usage dictates that
when used as a verb (action), it's 'log in' or 'logged in'. When used as a
noun or adjective (what is your login, or login information) it's one word.
'Sign in' is never one word.
