try this, but i did not test it.

local component=require("component")
local r=component.redstone
local gpu=component.gpu
local term=require("term")

---- config section
local password="1234"
local delay=5 --time the door stays open
local side=5 --side of the door, test this
-----

local wrong=false

while true do
  term.clear()
  gpu.set(1,1,"Please enter the password")
  if wrong then
    gpu.set(1,1,"Password was wrong, try again")
    wrong=false
  end
  term.setCursor(1,2)
  local input=io.read()
  if input==password then
     r.setOutput(side,15) -- check if this is the correct function
     os.sleep(delay)
     r.setOutput(side,0) -- same here
  else
     wrong=true
  end
end

You can also read nicknames from a touch event and do not use passwords at all - if passing nicknames to events is enabled in server config, of course. In most cases it is enabled.

You can use this code for passwordless door:

local user = { "user1", "user2", "user3" }
 
local red = component.proxy(component.list("redstone")())
local scr = {}
local gpu = {}
 
for a in component.list("screen") do table.insert(scr, a) end
for a in component.list("gpu") do table.insert(gpu, component.proxy(a)) end
for i = 1, #gpu do gpu[i].bind(scr[i]) end
 
function showState(s)
  for i, g in ipairs(gpu) do
    g.setResolution(40, 20)
    g.fill(1, 1, 40, 20, " ")
    if s then
      g.setForeground(0x00FF00)
      g.set(16, 10, "Access denied")
    else
      g.setForeground(0xFF0000)
      g.set(16, 10, "Access granted")
    end
  end
end
 
function sleep(x)
  local tgt = computer.uptime() + x
  while computer.uptime() < tgt do
    computer.pullSignal(tgt - computer.uptime())
  end
end
 
while true do
  showState(false)
  local type, _, x, y, btn, nick = computer.pullSignal(5)
  if type == "touch" then
    nick = nick:lower()
    for i, v in ipairs(user) do
      if v == nick then
        showState(true)
        red.setOutput(1, 255)
        sleep(2)
        red.setOutput(1, 0)
      end
    end
  end
end 

Modify user list on top of code, flash it to EEPROM, connect some screens, install same amount of GPUs and one redstone block. Program will trigger pulse on top side of it.

well that's also a way. but isn't your sleep function the wrong way to let the computer "sleep" and is calling os.sleep(x) not the better way?

You'd be surprised how OpenOS does it. Though the OpenOS version is slightly better, as it uses event.pull, which means that signals happening during sleep are properly passed on to any listener functions instead of being swallowed by the sleep loop.

It's a EEPROM code, there is no event.pull, so these functions are equivalent.

oh that makes perfectly sense! thanks!
