If the password is to be changeable then you will have to store it in a file, this will need the FS API

You may want to look into encrypting that file, there are several encryption APIs on the forums: http://www.computercraft.info/forums2/index.php?app=core&module=search&do=search&fromMainBar=1

Logging in is asking the user to input something and then comparing that to the password. If you have your program run the shell then they can logout with the exit command.

You will need to make the program run on startup, you may want to provide another file to startup from.

You should hash passwords when storing them. You don't need to encrypt them. Here's a good Hashing API: http://www.computercraft.info/forums2/index.php?/topic/8169-sha-256-in-pure-lua/

In develepment I have an Os that asks for a password system at startup

Here are the main password files:

–something/password–
–[leave field blank, press save, do not type this comment in]—

–startup–
shell.run('something/startup')

–something/startup-
passwordf=io.open('something/password','r')
password=passwordf:read()
passwordf:close()
print('Password Please?')
if password==nil then
term.clear()
term.setCursorPos(1,1)
shell.run('something/createpassword')
shell.run('file')
else if read('*')==password then
shell.run('file')
else
print('incorrect')
sleep(1)
os.shutdown()
end
end

–something/createpassword–
print('You neeeed a password. You can currently only have one password, and no usernames')
pw=io.open('NyanOs/password','w')
pw:write(read('*'))
pw:close()
