How to set a password to enter DOS?

Just add a judgment in AUTOEXEC.BAT, but you need to provide an input device, such as WABT or something like that

Can you explain it in detail?

You need to disable Ctrl+C first, heh.

call w.bat box (+white on +blue) @autoexec.bat:mima
boff>nul
if errorlevel 100 goto next
if errorlevel 4 off.com
if errorlevel 3 restart.com
if errorlevel 2 goto find
:mima

This is a password program I wrote myself. You can put boff earlier for more security

Pure DOS doesn't have encryption functions. It's possible to make a DOS shell by yourself.

F4......F5...... can all make the DOS start cleanly.

Can you explain it in detail? Also, what is the content of w.bat? Can you make it public?

E:\>autoexec1

E:\>call w.bat box (+white on +blue) @autoexec.bat:mima

E:\>boff1>nul
'boff' is not an internal or external command, nor is it a runnable program
or batch file.

E:\>if errorlevel 100 goto next
The system cannot find the specified batch label - next

E:\>

Agreed

First, in order to achieve real security, it is necessary to modify IO.SYS first to block the function of pressing the F8 key during boot to enter the boot selection menu. Second, load a program to block the keyboard according to the instructions in CONFIG.SYS. When a password needs to be entered, first allow keyboard input, and then immediately start the password verification program. When writing this program, code to prevent CTRL+C should be added.
