• Self service depends on non-password credentials:
    • Security questions.
    • Mobile phone number.
    • Personal e-mail address.
    • App on smart phone.

  • This data rarely exists prior to deployment.
  • New hires must enroll too.
  • ROI depends on user adoption:
    • Users tend to ignore invitations.

  • Identify users with incomplete profiles.
  • Invite them to sign up. Send reminders with increasing urgency:
    • E-mail.
    • Open browser at login time.
    • Forced enrollment (full screen, locked browser.)

  • Throttle invitations:
    • Per user (e.g., once a week).
    • Overall (e.g., 500/day).
