Passkeys: 5 Deployment Tips for Identity

Key insights

• Passkeys rollout is more than a setting — treat it as a product rollout that changes authentication, support, and operations.
  Plan for user training, help-desk impact, and phased change rather than a one-click switch.
• Vincent Delitz (Corbado) has run large-scale CIAM passkey deployments and highlights often-missed Day 2 issues like support spikes and edge-case failures.
  Expect real-world deployment problems that vendor docs may not cover.
• Microsoft is shifting to passkeys as the expected path and introduced an automatic passkey rollout for Entra ID.
  If attestation is enabled the default allows only device-bound passkeys; if disabled it allows both device-bound and synced passkeys. Existing campaign targeting and configurations are preserved.
• Five practical rollout lessons identity teams should follow:
  • Treat rollout as a program — stage readiness checks, registration, then enforcement.
  • Choose passkey type early — decide device-bound vs synced based on attestation policy.
  • Review targeting — inherited campaign assignments need auditing before rollout.
  • Plan for user adoption — device readiness and communication matter as much as config.
  • Phase enforcement — test, register, then require passkeys with Conditional Access.
• Key benefits to highlight: phishing-resistant credentials, higher sign-in success rates than passwords, and a simpler user experience that reduces password resets and help-desk load.
  These advantages make passkeys a strong long-term security and UX win when rolled out properly.
• Practical tips and common pitfalls: staging with campaigns and readiness checks, verify device readiness across platforms, monitor metrics for misleading success rates, and prepare support teams for Day 2 problems like device or network edge cases.
  Test on representative user groups, instrument registration and sign-in metrics, and phase enforcement to limit disruption.
