After dealing with password policy impacts across multiple PLM implementations, here’s what I’ve learned about balancing security with usability:
Password Complexity Rules - Modern Approach
Your current policy (12 chars, special characters, 90-day expiration, 12 password history) follows outdated security guidance. The 2017 NIST Digital Identity Guidelines (SP 800-63B) fundamentally changed password recommendations based on research showing that traditional complexity rules create poor user behavior.
Modern best practices:
- Minimum length: 12-15 characters (you have this right)
- Complexity: Remove special character requirements - they don’t significantly increase entropy but dramatically increase user frustration
- Expiration: Eliminate calendar-based expiration (90 days) - it encourages predictable patterns like “Summer2024!” then “Fall2024!”
- Instead: Expire passwords only when compromise is detected or suspected
- Password history: Keep this, but 12 iterations may be excessive - consider 5-6
- Add: Screen passwords against known breach databases (Have I Been Pwned API)
For recipe management with diverse user populations, implement risk-based policies:
- Read-only users (production floor): 12 chars, no complexity, no expiration, optional MFA
- Recipe editors: 15 chars, no complexity, no expiration, mandatory MFA
- System admins: 20 chars, no complexity, no expiration, mandatory hardware token MFA
The key insight: Length provides security, complexity provides frustration. A 16-character passphrase like “coffee-recipe-production-2024” is far stronger and more memorable than “C0ff33!Rx”.
Self-Service Reset Tools - Implementation Reality
Self-service password reset (SSPR) can reduce help desk load by 60-80%, but only with proper implementation:
Critical success factors:
- Pre-enrollment during user onboarding (don’t wait until they’re locked out)
- Multiple verification methods (mobile SMS, personal email, security questions, authenticator app)
- Prominent placement on login page and in user communications
- Simple, intuitive user interface (test with actual production floor users)
- Integration with your identity management system for real-time password sync
Common failures:
- Users don’t know SSPR exists (communication problem)
- Verification methods aren’t set up in advance (process problem)
- Interface is too complex for occasional users (design problem)
- Reset doesn’t sync across all systems immediately (integration problem)
For TC 12.3 recipe management, ensure your SSPR tool:
- Syncs password changes to Teamcenter’s user directory within 30 seconds
- Sends confirmation notifications to prevent unauthorized resets
- Logs all reset attempts for security audit trail
- Works from shop floor terminals (not just corporate network)
- Supports users who don’t have corporate email (use mobile as primary contact)
MFA Alternatives - Equivalent Security, Less Friction
Modern authentication methods that reduce password burden:
-
Biometric Authentication: Windows Hello, Touch ID, Face ID on endpoints. Users authenticate with fingerprint or face scan, no password needed. Requires biometric-capable devices but provides excellent security with zero cognitive load.
-
FIDO2 Security Keys: Hardware tokens (YubiKey, etc.) that users tap to authenticate. Stronger than passwords, immune to phishing, no memorization required. Cost is $20-50 per user but eliminates password support costs.
-
Mobile Push Notifications: Users approve login attempts via smartphone app (Duo, Okta Verify). Good for users who don’t have biometric devices. Requires smartphone and network connectivity.
-
Proximity Cards/Badges: For shared shop floor terminals, use existing physical access badges as authentication factor. Pair with PIN for two-factor auth without password complexity.
-
Passwordless Authentication: Eliminate passwords entirely using certificate-based authentication or FIDO2. Users authenticate with device possession + biometric. Highest security, lowest friction, but requires infrastructure investment.
For recipe management specifically, I recommend:
- Production floor operators: Badge + 4-digit PIN (fast, no memorization)
- Mobile users: Biometric on smartphone/tablet
- Desktop engineers: Windows Hello biometric or FIDO2 key
- External partners: Mobile push notification MFA
This provides strong authentication appropriate to each user context without the cognitive load of complex passwords.
Practical Recommendations
To reduce your current friction while maintaining security:
- Immediately: Extend password expiration from 90 to 365 days (or eliminate)
- Within 30 days: Deploy self-service password reset with proactive user enrollment campaign
- Within 60 days: Implement risk-based password policies (different rules for different roles)
- Within 90 days: Pilot passwordless authentication with production floor users
- Within 6 months: Migrate to passphrase-based passwords (length over complexity)
Monitor help desk ticket volume, user satisfaction scores, and security incident rates to validate that changes maintain security while improving usability. The goal is invisible security - users should rarely think about authentication because it just works.
