Increase password prompt timeout for CentOS 7

  • 772

We are usually using ssh + keys to access our servers.

Recently I had to give a password to another person to enter into the login prompt in person at the client location, with monitor and keyboard and all. I wanted secure servers so I set all passwords to 50 random characters. Never actually tested that a normal person can enter them.

The problem is that shortly after you start entering the characters the password prompt resets. I'ts not that shortly, but its 50 characters...

Can I somehow get that timeout increased?

PS. I'm talking about this screen: enter image description here

    This should be possible to set in /etc/login.defs with the value LOGIN_TIMEOUT.

    http://man7.org/linux/man-pages/man5/login.defs.5.html

           LOGIN_TIMEOUT (number)
           Max time in seconds for login.

  2. Change Login Grace Time . set 1 minutes or 5 mins as per your requirements 

    vi /etc/ssh/sshd_config
LoginGraceTime 1m

    if wants to disable login session during ssh login set 

    LoginGraceTime 0
