Secure passkey transfer is a method for moving passkeys between credential managers without exporting them into a file. The user authenticates locally, and the credentials move directly between apps in a standardized format, reducing the risk of leakage while preserving portability and user control.
Expanded Definition
Secure passkey transfer is the controlled movement of a passkey between credential managers without turning it into an export file that can be copied, forwarded, or left behind. It is designed for portability, but it is not the same as password export, key backup, or account recovery.
The important boundary is trust in the transfer path itself. A secure transfer keeps the credential encrypted and bound to a local user-authenticated flow, so the receiving app can import it without exposing the raw secret in a reusable format. That distinction matters because a passkey is a cryptographic credential, not a simple convenience artifact. Standards and platform behaviour continue to evolve, so implementations may vary across ecosystems; readers should treat vendor wording carefully and look for actual transfer guarantees rather than generic “sync” language. The broader identity context is well covered in the OWASP Non-Human Identity Top 10, which is useful when transfer patterns intersect with credential handling and control boundaries.
A common misunderstanding is assuming that any move between apps is safe if the user approved it. In practice, secure passkey transfer only holds if the source, transport, and destination all preserve confidentiality, authenticity, and intended user control.
Examples and Use Cases
Secure passkey transfer appears in everyday credential portability workflows, especially when a user changes devices, adopts a new manager, or consolidates credentials after a platform migration.
- Moving a passkey from one password manager to another while keeping the credential encrypted during the handoff.
- Transferring credentials from a phone-based authenticator app into a desktop manager for better cross-device availability.
- Replacing a consumer account setup with a new enterprise-approved credential manager without forcing users to re-register every passkey.
- Preserving access continuity during device replacement, where the user needs portability but not a downloadable file that can be reused elsewhere.
The tradeoff is convenience versus control. The more seamless the experience, the more important it becomes to verify that the transfer is locally authenticated and not dependent on a brittle export/import format that broadens exposure.
For teams studying the operational side of credential handling, Ultimate Guide to NHIs is useful background because it shows how portability decisions can affect credential lifecycle visibility.
Security Implications
Secure passkey transfer reduces the obvious leakage risk of file-based export, but it also creates a new trust boundary: the transfer mechanism itself. If that boundary is weak, the transfer can become a covert path for credential duplication, unauthorized import, or user confusion about where the authoritative copy resides.
Failure usually shows up as uncontrolled credential sprawl, weak inventory of where the passkey exists, or hidden persistence after a user thinks a credential was “moved.” That is especially dangerous for high-value accounts because a transferred passkey still grants the same authentication power as the original.
Failure mechanism: the source app, transfer channel, or destination app fails to preserve exclusive user control, allowing the credential to be copied, retained, or imported into an unintended environment.
Impact: account recovery becomes harder to reason about, revocation becomes less reliable, and the organisation may lose visibility into how many credential managers now hold the same passkey. NHIMG notes that only 5.7% of organisations have full visibility into their service accounts, which is a useful reminder that visibility gaps tend to widen when credentials can move freely across tools.
Domain and Governance Relevance
In identity governance, secure passkey transfer matters because portability changes ownership, inventory, and offboarding expectations. A transferred passkey is still an identity-bearing credential, so governance must answer who can move it, where it can land, and how the source of truth is recorded.
For NHI-adjacent environments, the same logic applies to machine and delegated credentials: if credentials can be transferred without clear control, teams lose assurance about custody and scope. That is why transfer design should be treated as part of the credential lifecycle, not as a convenience feature separate from policy. The strongest governance question is whether the organisation can still locate, attest, and revoke the credential after transfer.
When passkeys are used in mixed human and machine-access ecosystems, the control lesson is simple: portability is acceptable only when it does not weaken auditability, revocation, or boundary enforcement.
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 CIS Controls v8 and NIST Zero Trust (SP 800-207) set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-02 — Secrets and Credential Management | Secure passkey transfer handles credential custody and movement. |
| Recommendation — Restrict passkey movement paths and preserve custody controls across credential managers. | ||
| CIS Controls v8 | 5 — Account Management | Passkey transfer affects account lifecycle and ownership continuity. |
| 6 — Access Control Management | Transfer changes who can hold and use the credential. | |
| 8 — Audit Log Management | Transfer events need visibility for credential custody and review. | |
| Recommendation — Track where transferable credentials exist and remove stale copies during offboarding. Limit transfer authorization to approved users and trusted managers. Log credential transfers so you can detect unexpected movement and validate custody. | ||
| NIST Zero Trust (SP 800-207) | 3 — Device Trust Policy | Passkey transfer depends on trusted endpoints and local authentication. |
| Recommendation — Allow transfers only between trusted devices that meet your access policy. | ||
