encrypted password

When I typed it in then confirmed it, it said passwords don't match and it never actually took any of my passwords, regardless of how many different passwords, both simple and complex, I tried. When looking at the step by step through google, I never made it past "set a password that you'll remember" because it never accepted any passwords that I tried.

But I am seeing confirmation that a backup was completed and time stamped for last night, so I am trying to access that backup and its asking me for a password, which again, never went through. So I didn't even think the backup went through, but I see one there.

It never took a password in the first place- so there has to be an automatic password that was generated or some place I can look for it on my computer...
