The process of moving passkeys into or out of a credential manager or platform. In secure implementations, this should use standardized, encrypted exchange methods rather than flat files. The main challenge is preserving interoperability and security at the same time during migration.
How Passkey Import And Export Works
passkey import and export is a migration function, not a new authentication method. It exists so users and organisations can move passkeys between approved credential managers, platforms, or devices without re-enrolling every credential from scratch.
The secure model matters because the passkey itself is the trust anchor. If export degrades into a plain file, or import relies on weak handling, the migration path becomes the easiest place for exposure. That is why standardized, encrypted transfer flows are preferred over ad hoc file movement or manual copy techniques.
In practice, the feature has to preserve both usability and binding. A passkey should remain tied to the correct user, device, and relying party relationship after transfer, or the migration may succeed technically while breaking the security guarantees that made the passkey valuable in the first place.
Why Interoperability Matters
Import and export become important when organisations change platforms, replace devices, support multiple ecosystems, or recover after loss of access. Without a portable but protected transfer method, passkeys can become trapped in one manager, which creates operational friction and weakens adoption.
The interoperability challenge is that passkeys are not just generic secrets. They are cryptographic credentials embedded in platform and authenticator ecosystems, so export and import must preserve enough structure for another supported manager to accept them safely. That requirement is the reason standardized exchange formats are central to the term.
Well-designed portability also reduces the temptation to fall back to weaker alternatives. If migration is hard, users and administrators are more likely to revert to passwords, shared accounts, or unsafe export workarounds, which undermines the security benefit passkeys were meant to deliver.
Security Boundaries During Transfer
Export is the more sensitive direction because it creates a moving credential that can be intercepted, copied, or mishandled. Import is also sensitive because the receiving system must validate provenance, decrypt the payload correctly, and place the passkey into the right trust context without weakening the original binding.
Secure implementations therefore rely on encrypted packaging, authenticated transfer paths, and platform-level controls that limit where the credential can be exported, how long the transfer artefact remains valid, and what happens if the process is interrupted. NIST SP 800-63 Digital Identity Guidelines is useful background because passkeys sit inside modern phishing-resistant authentication models.
For a broader control lens, NIST SP 800-53 Rev 5 Security and Privacy Controls maps well to the access control, identification and authentication, audit, and configuration disciplines involved in protecting credential transfer. The same transfer path should also be reviewed against OWASP API Security Top 10 when the migration flow is exposed through application or platform APIs.
What Good Migration Design Looks Like
Good design treats import and export as controlled lifecycle events. That means the feature should be explicit, user-initiated or administrator-approved where appropriate, and constrained to trusted destinations rather than exposed as an always-on data dump.
The transfer should be cryptographically protected end to end, with clear boundaries for authentication, authorization, and integrity checking. The receiving side should reject malformed or unauthorised payloads, and the source side should avoid leaving reusable artefacts behind after the operation completes.
Documentation also matters. Users and support teams need to know which ecosystems are compatible, what happens when a device is lost, and whether the transfer preserves sync state, key metadata, or account recovery expectations. Without that clarity, portability can look simple while actually hiding dependency and recovery risk.
Risk and Threat Considerations
Passkey import and export create a concentrated exposure point because they move high-value authentication material across trust boundaries. If the migration process is poorly encrypted, overly permissive, or exposed through a weak application path, it can become a convenient way to steal or duplicate credentials.
Failure mechanism: Attackers, malware, or careless administrators can abuse export artefacts, insecure temporary storage, or weakly protected transfer APIs to capture passkeys before they are imported into the target manager.
Impact: A compromised migration path can enable account takeover, credential replay into supported relying parties, or long-lived exposure if exported material is retained, copied, or shared outside the intended ecosystem.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
NIST SP 800-63, CIS Controls v8 and NIST CSF 2.0 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST SP 800-63 | Digital Identity Guidelines — Digital Identity Guidelines | Passkey migration sits inside phishing-resistant digital identity and authenticator handling. |
| Recommendation — Apply SP 800-63 guidance to preserve authenticator assurance during passkey transfer. | ||
| CIS Controls v8 | 6 — Access Control Management | Passkey export and import govern who can move and reuse authentication material. |
| Recommendation — Restrict passkey transfer paths to approved users, systems, and destinations. | ||
| NIST CSF 2.0 | PR.AA — Identity Management, Authentication, and Access Control | Passkey portability depends on controlled authentication and access decisions during lifecycle movement. |
| PR.DS — Data Security | Exported passkeys are sensitive data that require protected handling and secure transport. | |
| GV.RM — Risk Management Strategy | Passkey transfer design requires explicit risk decisions about portability versus exposure. | |
| Recommendation — Enforce identity and access controls around passkey import and export operations. Protect exported passkey material with encryption and controlled handling. Set policy for approved passkey migration methods and acceptable transfer risk. | ||
Practitioner Guidance
Governance implication: Treat passkey transfer as a privileged credential-lifecycle event, not a convenience feature. Ownership should sit with identity, platform, or security teams that can define which destinations are approved, how transfers are logged, and when recovery or device replacement is allowed.
What to watch for: Watch for implementations that still rely on flat files, unmanaged backups, or undocumented sync behaviour. Those patterns usually indicate that the system is solving portability at the expense of credential protection, which defeats the purpose of passkeys.
