A password manager can sync passkeys across devices, support multiple operating systems, and make controlled sharing easier. A device-only ecosystem may keep credentials tied to one vendor or one device family, which limits portability and can complicate collaboration. For teams, the real distinction is operational flexibility versus tighter ecosystem lock-in.
How the two storage models change day-to-day use
The practical difference is not just where the passkey lives, it is how the passkey behaves across a team’s devices and workflows. Password-manager storage is usually designed for portability, cross-platform use, and controlled access across approved devices. Device-only ecosystems usually optimise for a tighter native experience inside one vendor family, which can improve simplicity but reduce flexibility.
That means the same passkey can support very different operating models. A shared password manager can help when people use multiple endpoints, need to move between operating systems, or must recover access without being tied to one device. A device-only model can be fine for personal use or tightly standardised fleets, but it is less forgiving when users change hardware, work across platforms, or need to coordinate access.
For passkey architecture and recovery design, see Passwordless and Passkeys Guide and Workforce Identity Security Guide.
Where portability becomes an operational control decision
Portability is the main trade-off. Password-manager-backed passkeys can reduce lock-in because the same credential set may be available on more than one approved device, which helps with business continuity, offboarding, device replacement, and mixed-platform environments. That flexibility is especially useful when the operational goal is to keep access recoverable without forcing everyone onto the same ecosystem.
Device-only passkeys shift the balance toward ecosystem consistency. They can be easier for a single-user workflow because the sign-in experience is tightly integrated with one vendor’s account and device model, but that convenience comes with a dependency on the vendor’s recovery path and the user’s ability to stay inside that ecosystem. If a team values portability over simplicity, password-manager storage is usually the more adaptable choice.
For ecosystem portability and recovery behaviour, consult NIST SP 800-63 Digital Identity Guidelines.
Collaboration, recovery, and lock-in are the real differentiators
The biggest difference shows up when passkeys must be shared, recovered, or managed at scale. Password managers are often better suited to controlled collaboration because they can support organised access to approved credentials and reduce the need to rebuild access from scratch when a device is replaced. Device-only ecosystems usually make collaboration more awkward because access is more closely tied to one person’s device set and one vendor’s recovery process.
That does not make device-only storage insecure by default. It means the operational questions are different: who can recover access, how quickly can access be restored after a lost device, and how much vendor dependency the organisation is willing to accept. In practice, the choice often maps to whether you want centralised control over credential portability or a simpler but more bounded native experience.
For teams evaluating the downside of over-tight ecosystem coupling, the broader identity and access control model is also relevant in LastPass breach 2022.
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, NIST CSF 2.0 and CIS Controls v8 set the technical controls, while ISO/IEC 27001:2022 defines the regulatory obligations.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST SP 800-63 | Digital Identity Guidelines | Passkeys and recovery choices directly depend on authenticator assurance and phishing-resistant authentication guidance. |
| Recommendation — Apply NIST 800-63 guidance to choose authenticators and recovery methods that fit your portability and assurance needs. | ||
| NIST CSF 2.0 | PR.AA-05 — Identity Management, Authentication, and Access Control | The question is about how passkey storage affects authentication control and access portability. |
| Recommendation — Use PR.AA-05 to keep authentication, recovery, and access decisions aligned with the chosen storage model. | ||
| ISO/IEC 27001:2022 | A.5.15 — Access control | Passkey storage affects who can access accounts and how that access is governed across devices. |
| Recommendation — Define access control rules for passkey use, recovery, and approved device enrollment. | ||
| CIS Controls v8 | CIS-5 — Account Management | Passkey portability and recovery are shaped by how accounts are provisioned, transferred, and removed. |
| Recommendation — Standardise account lifecycle handling so passkey access stays recoverable and removable. | ||
Practitioner Guidance
What to prioritise: Decide first whether your environment values portability and cross-platform recovery more than native simplicity. If users move between operating systems or devices, a password-manager approach is usually easier to operate safely at scale.
What to verify: Test the recovery path before rollout, including new-device enrollment, lost-device replacement, and account transfer rules. The right answer is the one that can be recovered without creating an informal help-desk workaround or a one-off exception process.
Decision rule: If the credential must support team continuity, mixed endpoints, or vendor independence, prefer a password manager. If the passkey is intended for a tightly standardised personal workflow and ecosystem lock-in is acceptable, device-only storage may be sufficient.
Practitioner takeaway: The key question is not “which is safer in the abstract”, but “which storage model gives the organisation the recovery, portability, and control it actually needs without unnecessary lock-in.”
