How to compare a variable to a certain value, if it has the value the script should continue in CMD

I have tried this code in my .batch file

@echo off

Title Ping

color b

echo Enter the website you would like to ping

set input=

set /p input= Enter your Website here:

color d

echo Enter the password for the program

set input2=

set /p input2= Enter the Pass here:

color b

IF [input2] EQU [1234]

It should check if Input2 is equal to 1234 and if it is the script should continue, if it is not equal to 1234 it should just wait. I guess it is pretty simple but i dont seem to get it working. also script just crashes after the last line of code.
