I used console command passwd to change my own password that I set straight after the OS installation with useradd command. My original password contained only line characters, without capitalization, numbers or special characters, but passwd prohibits me to set similar (only line characters) password. Why useradd was less strict than passwd? Is there any way to set "simple" password for already existing user?
P.S. I understand that such requirements are often suggested for security reasons, but this my own laptop and my own system.
