Password Protect (Set passwords as well)

its easy enough…make it create a file with the password on it and then have the program read the password from the file…this would mean u can change It aswel
what's the code u have already?

this will do what you want, hope it helps
Have as startup on a disk

if fs.exists("startup") == false then
fs.copy("disk/SecSystem","startup")
shell.run("startup")
end

Have this on a disk called like "SecSystem" or whatever u want it as just make sure u change the code above to match

function login()
term.clear()
term.setCursorPos(1,1)
print("Welcome To blah blah Security System")
write("Please Enter the Access Password: ")
pass = read("*")
local f = fs.open( "password.txt", "r" )
apass = f.readLine(newpass)
f:close()
if pass == apass then
-- your code here when pass is correct
else
-- your code here when pass is wrong
end
end

if fs.exists("password.txt") == false then -- this is the part that will set the password
term.clear()
term.setCursorPos(1,1)
print("Please Type a New Password")                   
newpass = read()
local f = fs.open( "password.txt", "w" )
f.write(newpass)
f:close()
login()
else
login()
end

You need to put the code checking for a password at the top of the code, else it'll never check for the password.

I use a default code for a password off of this forum, just altered a bit to my needs… What I wanted to do is add some code onto it to make it have you set the password ingame for the first time… If you get what I mean…

You can have my copy.

The settings file is unencrypted, but it is highly secure except for initial set up.
EDIT:
This also moves the current startup to startup.bak to prevent accidental overwrites, but only saves one .bak.

Uh, sorry, I haven't been able to connect to this site for about a month whatsoever.. The code that I have is…

os.pullEvent = os.pullEventRaw
local side = "left"
local password = "1412114"
term.clear()
term.setCursorPos(1,1)
write("nnnnnnPlease Enter The Password:nnnn> ")
local input = read("*")

if input == password then
term.clear()
term.setCursorPos(1,1)
print("Password Correct! Quarry Turned On!")
rs.setOutput(side,true)

else
term.clear()
term.setCursorPos(1,1)
print("Password incorrect! Quarry Not Turned On!")
sleep(2)
os.reboot()
end

local input = read()

if input == "reboot" then
write("ERROR: You may not reboot this computer at this time! nnTo Turn Off Quarry, Type Off")

elseif input == "Off" then
shell.run("quarryoff")
end

Yeah, I made a 'quarry lock' for a friend, and since I am a noob at Lua, I had it run external files at times…

Anyway, I understand the part where you are supposed to get the code to check for a password but the code that is needed is the code that I am asking for since I don't know it.

Also, this is old code now, this is just the password part, and when the password is correct, I make it toggle the redstone output rather than having a player type 'On or Off'. If that helps whatsoever.

I didn't see this post XD. Hey. Could you tell me what "f" means? Like 'local f'? Thanks, that would really help me :3

'f' is just a variable.
In this case, 'f' has been assigned to 'fs.open()', meaning you don't have to type 'fs.open' every time - you can just type 'f'!

It's also used to make the code easier to read.
It doesn't matter what the name of the variable is as long as it's something logical, so you can remember what it is, but the name is case sensitive, so 'var' and 'Var' are completely different variables (in this case, 'f' probably stands for 'file', as 'fs.open()' is used to open the file directory in the brackets).

The 'local' part means that the variable is only used by this 'chunk' (part of) the code, and if you try to access 'f' in a different chunk, it won't be the same variable. This means that sections of code using variables with the same name won't interfere with each other. It is good habit to use local variables as much as possible.

Ah thanks, this will help a lot. I didn't realize that you can do something like "[filename] = read()" and f.close, ect…
