Password policy guide
A modern password policy should reduce account takeover risk without forcing users into weak workarounds. Good policy emphasizes longer passwords, known-bad password screening, MFA, password managers, secure recovery, privileged-account controls, service-account governance, monitoring, and practical exception handling.

Why it matters
Use password policy to reduce real identity risk
Traditional password policies often focused on short complexity rules and frequent forced rotation. Modern guidance is more practical: allow longer passwords, block known-compromised or easily guessed passwords, avoid arbitrary periodic changes unless there is a risk reason, and require MFA for important access.
A strong policy also defines what happens outside normal user sign-ins: administrator accounts, shared accounts, service accounts, emergency access, recovery codes, vendor access, password managers, browser password storage, and offboarding.
The goal is not to make passwords painful. The goal is to prevent reuse, guessing, phishing, credential stuffing, unmanaged sharing, and forgotten exceptions that quietly create business risk.
Practical rule: Every password policy should define minimum length, banned-password screening, MFA requirements, password-manager expectations, rotation triggers, recovery controls, privileged-account handling, service-account ownership, monitoring, and review evidence.
Review scope
Password policy review areas
User password standards
Set practical length requirements, allow longer passphrases, block known-bad passwords, and avoid rules that encourage predictable patterns.
MFA and passwordless options
Require MFA for remote, cloud, privileged, and sensitive access while planning for passkeys or phishing-resistant options where feasible.
Password managers
Define whether an enterprise password manager is required, how shared secrets are stored, and how browser-saved passwords are handled.
Privileged and service accounts
Control admin, local admin, service, vendor, shared, and emergency credentials with vaulting, ownership, rotation triggers, and review.
Recovery and reset process
Protect password resets, account unlocks, recovery codes, help desk verification, and emergency access from social engineering.
Monitoring and evidence
Review failed logins, lockouts, password spray attempts, risky sign-ins, reset events, exposed credentials, and exception reports.
Review matrix
Password policy control matrix
| Area | What to verify | Questions to answer | Evidence |
|---|---|---|---|
| Policy design | Review minimum length, banned-password checks, reuse rules, rotation triggers, password manager guidance, and MFA requirements. | Does policy reduce risk without encouraging weak workarounds? | Approved policy, settings export, exception register, and user guidance. |
| Identity platforms | Review Microsoft Entra ID, Active Directory, Okta, Google Workspace, VPN, firewall, RMM, and business application settings. | Are password rules consistent across important systems? | Platform exports, screenshots, group policy, conditional access notes, and app settings. |
| Privileged access | Review administrators, local admins, shared admin accounts, emergency accounts, vendor accounts, and service accounts. | Are high-impact credentials controlled differently? | Admin inventory, vault report, rotation record, MFA evidence, and access review. |
| Recovery | Review self-service password reset, help desk reset process, account unlocks, recovery codes, and lost-device handling. | Could recovery be abused to bypass authentication? | Reset workflow, help desk script, identity proofing notes, and reset log review. |
| Monitoring | Review failed logins, lockouts, password spray detection, risky sign-ins, breached credential alerts, and reset events. | Can credential attacks be detected quickly? | Alert rules, log samples, SIEM queries, incident tickets, and review notes. |
| Review | Review exceptions, legacy systems, inactive accounts, MFA gaps, weak password findings, and password manager adoption. | Is password risk improving over time? | Quarterly review, exception cleanup, remediation tickets, and executive summary. |
Step-by-step review
Password policy review runbook
1
Inventory authentication systems
List identity providers, directories, SaaS apps, VPNs, firewalls, RMM tools, privileged systems, service accounts, and password managers.
2
Compare policy to settings
Validate that platform settings match the approved password policy and identify systems with weaker or conflicting rules.
3
Review MFA coverage
Confirm MFA for remote access, cloud apps, privileged users, administrators, financial systems, email, and sensitive applications.
4
Assess privileged credentials
Review admin accounts, emergency accounts, service accounts, vendor accounts, local admins, shared accounts, and vault coverage.
5
Test recovery controls
Review password reset, help desk verification, account unlock, recovery codes, lost-device handling, and emergency access.
6
Review monitoring and alerts
Check failed logins, lockouts, password spraying, risky sign-ins, reset events, exposed credential alerts, and incident tickets.
7
Clean up exceptions
Document legacy gaps, assign owners, set expiration dates, add compensating controls, and track remediation.
Common risks
Common password policy mistakes
Short complexity rules dominate
Complexity rules can encourage predictable substitutions if length, screening, and MFA are weak.
Forced rotation is arbitrary
Frequent forced password changes without risk indicators can lead users toward weaker patterns and reuse.
MFA gaps remain
Password policy alone cannot protect remote access, email, admin consoles, cloud apps, and financial systems.
Service accounts are unmanaged
Non-human accounts often keep old passwords, broad privileges, unclear ownership, and no rotation plan.
Recovery is too easy
Weak help desk reset processes can bypass strong passwords and MFA through social engineering.
Exceptions never expire
Legacy applications and special accounts need owners, compensating controls, and review dates.

Password policy must fit real user behavior
A modern password policy lowers risk when it combines longer passwords, MFA, password managers, strong recovery, privileged-account controls, and monitoring.
FAQ
Password policy FAQ
Should passwords expire every 90 days?
Modern guidance generally favors risk-based changes instead of arbitrary forced rotation, unless there is compromise, role change, or a specific compliance requirement.
Are complexity rules enough?
No. Length, banned-password screening, MFA, password managers, and monitoring are more useful than relying only on symbols and mixed-case rules.
Should admin passwords follow the same rules as users?
Privileged accounts should usually have stronger controls, including MFA, vaulting, tighter monitoring, limited use, and more frequent review.
What evidence should be retained?
Keep policy documents, platform settings, MFA coverage, reset procedures, admin account review, exception list, monitoring alerts, and remediation tickets.
