Can anyone help.  For security reasons I reset my admin password on my Macbook Pro a few days ago and didn't write it down.  Now I've forgotten it.  I didnt receive an installation disc when I purchased my Macbook Pro online - it didn't come with one-help

Please see question above, but also note, I have the Applecare Protection Plan but am unable to get through to anyone on a weekend and I desperately need to use my laptop this weekend.  I can't log in at all now as I've forgotten my admin password.  A few weeks ago I also changed the password on my husband's new MacBook Pro and again forgot the password.  I spoke to someone at Apple and they helped me to reset it within minutes, by restarting the computer holding Command+something else (I can't remember what it was). A black screen with writing came up and I had to type in something like "password" (not sure exactly).  Anyway, this was a very quick and efficient process but I didn't write it down unfortunately.  Does anyone out there know what to do?  Thanks in anticipation
