http://www.computercraft.info/forums2/index.php?/topic/17231-xlogin-the-fast-login-program/
To use the program in computercraft type: pastebin get fnrUKmgX startup
I highly recommend you change these:
Default username is name
Default password is 1234
There is no security or encryption for storing the login details, use this program at your own risk!

Report any bugs and give suggestions to improve my program.
