I added one user with myname(prashant) but i had not set any password for same user account. Still when i reboot(runlevel5), i os asked mi for password for same user account. I tried to login with without password as i not set, still authentication failure msg display. how it is possible?

OS : Cent os 6.4 I added more two users also but not beneficial. Please can any one tell me the reason and way to login with same user.

  • It sounds like you want to set an empty password for your user. Is that right? – dhag Nov 20 '17 at 20:57

From the useradd(8) man page:

   -p, --password PASSWORD
       [...] The default is to disable the password.

The way to allow login is to assign a password using passwd.

  • To allow login by using passwd it is ok, but when i need to use this command. I mean after just useradd or when. Because i added user already and restarted system. I am now using this command but it is setting password. Kindly let me know how i disable the password of created account and while creation of new account using useradd command how i disable the password. Thanks in advance. – Prashant Nov 20 '17 at 20:12
  • @Prashant Your question is unclear. Do you want to set passwd or not? – Arpit Agarwal Nov 20 '17 at 20:59
  • The question is clear: the OP wants to login and cannot because the system is asking for a password, even though none was set. – G-Man Nov 20 '17 at 21:07
  • Yes G-Man is correct, i just added user with useradd command and when i reboot machine it shows me to enter password for same user. – Prashant Nov 21 '17 at 10:56
