Question

I have used the script from “batch file which asks for username/password + registration” (topic already in stackoverflow)… here’s my question: Is there any way that i could add a lockout to a batch-file or execute a shutdown command after 5 incorrect attempts? (the timeout at the bottom is for 24 hours)
Example Situation:
Username: bobTESTattempt1
Password: 1234
[enter]
Password is incorrect 4 attempts remaining!

(the next 3 attempts are used)

Username: bobTestattempt5
Password 123342
[enter]
Password is incorrect 0 attempts remaining!
[enter]

ACCOUNT LOCKED OUT
TIMEOUT 86400

Answer 1

Here you go

@echo off
set counter=5
:CREDS
cls
if %counter% equ 0 goto :LOCKOUT
if %counter% lss 5 echo Password incorrect, %counter% attempts left
set /p un=Enter your username:
set /p pw=Enter your password:
if %un%==correctusername (
if %pw%==correctpassword goto :ALLOK
)
goto :WRONG

:WRONG
set /a counter-=1
goto :CREDS

:ALLOK
echo Creds ok, do whatever
pause >nul
exit >nul

:LOCKOUT
echo ACCOUNT LOCKED OUT TIMEOUT 86400
timeout /t 86400
goto :CREDS
