I created a new user:



$ sudo useradd -m Ari -p pass123


But when I went to login it said the password was incorrect, I know it's correct because I saved the command line log as a text file.



Other than that, at the same time I also created a group:



$ sudo groupadd testgroup1


and added the new account to it:



$ sudo usermod -a -G testgroup1 Ari


Why can't a log in?

The -p option is looking for an encrypted password:




-p, --password PASSWORD




The encrypted password, as returned by crypt(3). The default is to disable the
password.





Note: This option is not recommended because the password (or encrypted password) will
be visible by users listing the processes.

You should make sure the password respects the system's password policy.


You should use the following to change the password:



sudo passwd Ari



In order to use the -p option you must first encrypt the password. You can use some of the methods mentioned here such as:



$ mkpasswd
Password:
1puqSPGTnyi5o
$ sudo useradd -m Ari -p 1puqSPGTnyi5o


Note the mkpasswd utility is included in the whois package which can be obtained through apt

    Don't use openssl passwd, and especially not with -crypt. It uses the obsolete DES-based crypt function, which among other things is limited to only 8-characters passwords (and 2-character salts). The openssl on my system does support the MD5-based hash ($1$), but not the newer SHA2-based hashes ($5$ and $6$), which are the ones commonly used on Linux-systems.

  • If you need to batch change passwords, use chpasswd. By default it runs the change through PAM, so you get a) the same hashing as with passwd, and b) the passwords updated to whatever it is your system actually uses (in case you have e.g. LDAP). It also does support e.g. -c SHA512, too, if you do need to bypass PAM.
