Help with program?

I want a password before anyone can do anything on the computer and want to make it so I can take words put them on the monitor. and to where it activates a redstone signal behind the computer. All while being able to go onto a floppy disk. After I enter the password to get onto the computer during startup can I be able to type one word to make all of these actions happen? Thank you! :D/>

I know how to password a Program but how do I password a computer. Ive tried to look up numerous things on this but only program passwords come up. Thanks

I think this belongs in General, not Ask a Pro

Usually, Ask a Pro is where you ask questions about code that you already have

I stand corrected

No, General is where I throw requests to have programs written for them, this is a topic wherein the OP asks for advice on how to implement things.

Moonguy100, you'll be unable to completely lock down a computer with a password lock because a disk drive adjacent to the computer with a blank startup file on the floppy inside will bypass the computer's startup file, which gets around any password lock. You can create a program to display things on a monitor and set a redstone signal fairly easily, you'll want to look into the redstone API and the peripheral methods that monitors provide, both of which are documented on the wiki. There are also tutorials on the forums that can help you get started with those sorts of things.
