Batch file that asks for username / password + registration

I need a batch file that can register the user in itself. sort of:

@echo off
echo Choose an option:
echo     1:Register
echo     2:Login
Set option=
set /p option=Your option: 
if %option%==1 goto reg
if %option%==2 goto login
...
:reg
--The registration script--
goto login
...
:login
Set usr=
set /p usr=Username: 
if %usr%== goto pass
echo False username!
@pause
goto login
...
:pass
Set passw=
set /p passw=Password: 
if %passw%== goto success
echo False password!
@pause
goto login

So ... something like that. 'if% passw% == ", and if% usr% ==" "' === this should automatically do this at registration.

Well, if more than 1 person registered.

Hmmm. This is what I learned with:

@echo off
title REGISTERANDLOGIN
if exist programbase.dll goto login
if not exist programbase.dll goto register

:register
title Register
echo Register
echo.
echo Please fill in the blanks.
echo.
Set usrname=
set /p usrname=Username: 
Set passw=
set /p passw=Password: 
echo %usrname%>> programdata.dll
echo %passw%>> programbase.dll
goto login

:login
:begin
set usr=
set /p usr=Enter your username: 
if {%usr%}=={} goto :begin
set authenticated=
for /f "tokens=*" %%a in (programdata.dll) do (
    if {%%a}=={%usr%} set authenticated=true
)

if not defined authenticated (echo Invalid Username & goto :begin)

:passwo
set pass=
set /p pass=Enter your password: 
if {%pass%}=={} goto :begin
set authenticated=
for /f "tokens=*" %%a in (programbase.dll) do (
    if {%%a}=={%pass%} set authenticated=true
)
if not defined authenticated (echo Invalid password & goto :begin)

:loggedin
cls
echo Welcome.
@pause
exit /b 0

To check for an empty string, place quotation marks on both sides:

if "%usr%"==""

To add to a text file, use →

echo %usr%:%pass% >> passwd.txt

To iterate over the contents of a file, use for / f:

for /f "delims=: tokens=1,2" %%x in (passwd.txt) do (
  if "%%x"=="%usr%" then (
    set usrfound=true
  )
)
if "%usrfound%"=="" then (
  rem Register user
) else (
  rem Check password and succeed/fail
)

A really easy way to do what you ask for is to simply register and the login page that detects the files. For example, create a pair of directories, such as userSaves or passSaves. Then the system simply determines if the files exist at login:

:page
set /p usr=Username:
if exist mydir\LoginProgram\saves\userSaves\%usr% (
echo Valid Username.
pause
goto passentry
cls
 ) else (
echo Invalid Username.
pause
goto page
cls
)
:passentry
cls
set /p pass=Password:
 if exist mydir\LoginProgram\saves\passSaves\%pass% (
echo Valid Password. Welcome!
pause
goto whateverpage
cls
 ) else (
echo Invalid Password. Login failed.
pause
goto page
cls
)

Super simple code. Just do the same for registration.
