Reset Linux Password PAM.md

Reset Linux user password (bypass PAM pwquality)

When passwd or chpasswd rejects a weak password due to PAM policy, hash it directly with SHA-512:

echo "USERNAME:NEWPASSWORD" | sudo chpasswd -c SHA512

This skips the PAM password stack and writes the hash straight to /etc/shadow.
