Add the following line to "/etc/security/pwquality.conf" (or modify the line to have the required value):

ocredit = -1

Check Contents

Verify TOSS 5 enforces password complexity by requiring at least one special character using the following command:

$ sudo grep ocredit /etc/security/pwquality.conf /etc/security/pwquality.conf.d/*.conf
