Keep the public key, credential ID, device metadata, and verified state intact across the migration. Test the destination system in a staging environment first, then confirm that existing passkeys authenticate immediately after cutover. If any of those bindings break, users will need to re-enrol even if the data export succeeded.
Why This Matters for Security Teams
Passkeys are designed to remove password risk, but migrations can silently turn a strong authentication method into a support incident if the underlying bindings are not preserved. For security teams, the real issue is not “copying data” but preserving the credential’s public key, credential ID, device metadata, and verified state so the relying party still recognises the authenticator after cutover. That makes this closer to identity continuity than a routine database move.
This matters because migration failures often surface only when users try to sign in and discover that the new system treats them as unregistered. That creates re-enrolment churn, help desk load, and pressure to loosen controls. The Ultimate Guide to NHIs shows how frequently identity failures become operational failures, and the same pattern applies here when identity state is not preserved cleanly. Current guidance aligns with broader identity governance principles in the NIST Cybersecurity Framework 2.0, especially around access control and recovery resilience.
In practice, many security teams discover passkey migration defects only after cutover traffic hits production, rather than through intentional validation of credential continuity.
How It Works in Practice
A safe passkey migration is usually a controlled identity-state transfer, not a re-issuance event. The destination system must import the exact passkey record fields the relying party uses to validate an assertion. At minimum, that means keeping the public key and credential ID intact. If the platform stores attestation or authenticator metadata, that data should also survive the move so risk checks and device trust logic continue to work as expected.
Teams should stage the migration first and test with a representative set of authenticators, browsers, and device types. Validate that existing passkeys authenticate immediately after cutover, that step-up flows still behave correctly, and that recovery paths do not accidentally force re-enrolment. This is especially important where passkeys are tied to enterprise SSO, managed devices, or conditional access policies.
- Export and import the full credential record, not just a user directory entry.
- Verify that the destination preserves credential ID, public key, and verification state.
- Test login success before cutover and again immediately after cutover.
- Check whether the new platform normalises device metadata differently.
- Confirm that recovery and sync features do not create duplicate credentials.
The broader lesson from NHI operations is that identity artefacts are often more fragile than teams expect. The Ultimate Guide to NHIs highlights how lifecycle handling and visibility gaps can create hidden exposure, and that same discipline is needed here. Standards bodies also frame identity continuity as part of durable access governance in the NIST Cybersecurity Framework 2.0. These controls tend to break down when the destination platform re-encodes authenticator records, because the relying party no longer recognises the original binding.
Common Variations and Edge Cases
Tighter migration controls often increase project friction, requiring organisations to balance security assurance against timeline pressure and user disruption. The biggest tradeoff is between preserving authenticators exactly and taking shortcuts that appear to simplify the migration. There is no universal standard for this yet across every passkey vendor and identity stack, so teams should treat platform-specific behaviour as a validation requirement, not an implementation detail.
One common edge case is device-bound passkeys that do not move cleanly across ecosystems. Another is when a vendor claims export success, but the destination system silently changes the credential handle or verification status. In those cases, the migration may technically complete while still forcing re-enrolment. Best practice is evolving, but the operational rule is simple: if any binding changes, users are likely to lose seamless authentication.
Security teams should also watch for mixed populations where some users have synced passkeys and others have hardware-backed credentials. Those populations can behave differently after cutover, especially if the new system handles authenticator assurance or backup eligibility in a new way. That is why the migration plan should include rollback criteria and a user-impact check, not just data integrity checks.
For organisations already managing complex identity estates, the same lifecycle discipline that applies to NHIs in the Ultimate Guide to NHIs applies here: preserve the binding, validate the state, and assume the user experience will fail if either is altered.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP Non-Human Identity Top 10 address the attack and risk surface, while NIST CSF 2.0, NIST SP 800-63, NIST Zero Trust (SP 800-207) and NIST AI RMF set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST CSF 2.0 | PR.AA-1 | Passkey migration must preserve authenticated identity continuity. |
| NIST SP 800-63 | IAL/AAL/FAL | Passkey binding and assurance state affect authenticators and reauthentication. |
| NIST Zero Trust (SP 800-207) | JIT | Zero Trust depends on continuous verification of credential state and binding. |
| OWASP Non-Human Identity Top 10 | NHI-08 | Credential binding loss during migration mirrors NHI lifecycle integrity failures. |
| NIST AI RMF | AI RMF supports governance of identity continuity and operational risk. |
Verify migrated passkeys still authenticate under the same access assurance before production cutover.
