I couldn't quite say I fully understand your question, but if in doubts about anything related to batch scripting, I could recommend checking out this website <a href="http://www.allenware.com/icsw/icswidx.htm" rel="nofollow noreferrer">this website</a>. 

The tutorial is really exhaustive, easy to follow and has helped me a number of times before.

blocks|key|1268752|text|要测试空字符串，请用引号将两边括起来：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1268753|if+"%25usr%25"==""|code-block|syntax|javascript|1268754|要追加到文本文件，请使用>>|1268755|echo+%25usr%25:%25pass%25+>>+passwd.txt|1268756|要循环遍历文件的内容，请使用for+/f：|1268757|for+/f+"delims=:+tokens=1,2"+%25%25x+in+(passwd.txt)+do+(
++if+"%25%25x"=="%25usr%25"+then+(
++++set+usrfound=true
++)
)
if+"%25usrfound%25"==""+then+(
++rem+Register+user
)+else+(
++rem+Check+password+and+succeed/fail
)|1268758|在测试或调试期间，请确保echo处于打开状态。如果要在for循环或其他多行语句中设置和测试变量，请将以下代码放在文件开头附近：|1268759|setlocal+enabledelayedexpansion|1268760|任何时候你需要读取一个在代码块中可能已经改变的变量，使用!var！而不是%25var%25。|1268761|entityMap^0|0|0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|W|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|X|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Y|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|Z|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|10|8|@]|9|@]|A|$]]|$1|M|3|N|5|D|7|11|8|@]|9|@]|A|$E|F]]|$1|O|3|P|5|6|7|12|8|@]|9|@]|A|$]]|$1|Q|3|R|5|D|7|13|8|@]|9|@]|A|$E|F]]|$1|S|3|T|5|6|7|14|8|@]|9|@]|A|$]]|$1|U|3|-4|5|6|7|15|8|@]|9|@]|A|$]]]|V|$]]

To test for an empty string, put quotes around both sides:

<pre><code>if "%usr%"==""
</code></pre>

To append to a text file, use >>

<pre><code>echo %usr%:%pass% &gt;&gt; passwd.txt
</code></pre>

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

<pre><code>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
)
</code></pre>

During testing or debugging, make sure echo is on. If you want to set and test a variable inside a for loop or other multiline statement, put this near the start of the file:

<pre><code>setlocal enabledelayedexpansion
</code></pre>

and any time you need to read a variable that might have changed inside the block, use !var! instead of %var%.

It uses one file, but multiple users could run the bat file and connect to the file. It works by looping the TYPE and set/p commands repeatedly. Although it couldn't update the chat list by itself, you could update it by pressing Shift and 6, and hitting Enter.

Why not just compare input to a user file?
make a file for each user and maybie get a encryption and decryption program to run automaticly for max security.

exit|4031142|原因是:在中，处理成功登录后发生的事情的标签必须位于登录的中间，而不是位于登录的末尾，这样用户名/密码组合就可以附加到:+login.bat标签上。显然，您可以添加其他修饰并更改文件的名称，但这是我的基本设计。我喜欢它们的简洁和易懂。它们在100%25的时间里都像一个护身符。希望这能有所帮助！|4031143|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

I'm decently proud of this :)
This has two different files: login.bat which handles the login and login2.bat which handles the registration.
login.bat:

<pre><code>@echo off
choice /c:RL /m "Choose an option: Register (R) or Login (L).:
if errorlevel 2 goto login
if errorlevel 1 goto register
:register
start /wait C:\[path]\login2.bat
cls
goto login
:in
cls
echo Welcome %u%
echo.
echo Bla Bla Bla or start "a program"
pause
exit
:login
set /p u=Username
set /p p=Password
</code></pre>

and login2.bat:

<pre><code>@echo off
:a
set /p a="Choose a Username"
set /p b="Choose a Password"
echo.
choice /m "Are you sure you would like your Username to be %a% and your Password to be %b%?"
if errorlevel 2 goto a
set q="if %%u%% equ %a% if %%p%% equ %b% goto in"
for /f "tokens=*" %%I in (%q%) do set m=%%I
echo %m% &gt;&gt;C:\[path]\login.bat
exit
</code></pre>

The reason why :in, the label which handles what happens after you login successfully has to be in the middle instead of at the end of login.bat is so that the username/password combinations could be appended to the :login label. Obviously you could add other embellishments and change the name of the files, but this is my basic design. I like how short and comprehensible these are. And they work like a charm 100% of the time.
Hope this helps!

I'm not providing full source code because all of you probably know how to do this.

A really easy way to do what you're asking is to just have a registration and a login page that detects files. Just make a couple directories like userSaves or passSaves for example. Then you have the system just detect whether or not the files exist on login:

<pre><code>: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
)
</code></pre>

Super simple code. Just do the same thing for registration.

I would like a batch file that can register a user into itself.
something like:

<pre><code>@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
</code></pre>

So... something like that. 'if %passw%== "" and if %usr%== ""' === it should automatticly make that at registration.

It will be nice if more than 1 people could register.

batch file which asks for username/password + registration
