Unique passwords everywhere
Credential stuffing reuses leaked email/password pairs from one breach against other sites. Unique random passwords contain blast radius to a single service.
Passphrases and length
Sixteen or more characters from a large alphabet outlasts “P@ssw0rd!” style rules. Passphrases of four random words can exceed entropy of short complex passwords if the word list is large enough.
Rotation without theater
Rotate when compromise is suspected or policy requires it—not on arbitrary 90-day calendars for low-risk accounts if NIST-style guidance applies to your org.
Integration secrets
API keys and webhook secrets belong in vaults with audit logs, not in ticket comments. Generate high-entropy strings and inject via environment at runtime.
