linux username and password removal

Question

Hello , 
 
 I am using ADSP SC589 custom board. I am new to linux. I am running linux OS on ARM. 
 While booting, console is asking username and password and by giving "root" I am able to login. 
 I want to remove these two security checks so that system can autoboot. 
 Also suggest how to set user specific username and password? 
 
 Regards, 
 GBiswal

Hi GBiswal462 , 
 To remove the password in buildroot, you could change the inittab file in output/target just like below. But note that this operation is not secure so we do not suggest to do this. 
 vim buildroot/output/target/etc/inittab # Put a getty on the serial port - ttySC0::respawn:/sbin/getty -L ttySC0 57600 vt100 # GENERIC_SERIAL + ttySC0::respawn:/bin/sh 
 Then make linux-rebuild;make to generate a new uImage file which does not need the login operation. 
 Let us know if you have more questions. Thanks!)
