Logging in to Steemit from another computer

Has anyone else had a problem with logging in from another computer that they don't normally use. I am staying logged in on my main computer, but taking my laptop with me when I travel, and I find that I can't login on my laptop. I've tried multiple times to put in my Steemit key, (which I assume is meant when asked for my password)....but it tells me that it's incorrect. so I typed it in to a note so that I could check it against the one I have stored in a hard copy...because there's no way I could type out the complicated 52 character computer generated KEY/Password without error...then clipped and pasted but no luck.

I am afraid to tinker with changing the password on my main computer....in case I jigger something up so that I can no longer log in there either.... It would be nice if I could just use a password of my own devising...
