Public service announcement: "login" is a noun; as a verb, you should write "log in". (Consider "knockout" vs. "knock out".) Another thing to watch out for: writing "setup" instead of "set up".
I don't interpret a meaningful difference between "can not" and "cannot," nor between "any more" and "anymore;" thus, I don't find a meaningful difference between "in to" and "into."
Noun: LOGIN => - a LOGIN - some LOGINS

We avoid mic (verb) because the "k" works so much better than "c" when leading into various verb endings like -ed and -ing. It's the same reason we add "k" to the word traffic to form words like trafficking; we would interpret the "c" softly ("s" sound) if it was followed by a vowel. But in this case we replace it with "k" instead of adding "k" to maintain the long "i" which would shorten if followed by more than one consonant.
Mic (noun only) is great as a truncation of microphone, though.
