Passkeys Across Platforms: Test Recovery Paths
A passkey sign-in works on one device but a user changes phones. This guide gives you a small, testable way to approach the issue before changing a live system.
A practical workflow
- Use standards-based WebAuthn or platform APIs and provide account recovery routes.
- Test cross-device use, cancellation and a device without an eligible credential.
What to check
Do not assume a passkey is automatically available on every platform or account. Compare the result with the original problem and record what changed. If a measurement or test does not support the change, revisit the assumption rather than adding more complexity.
Keep the experiment small enough to reverse. Document the starting state, the change and the result so another person can repeat the process. Product menus and versions can change, so check the current documentation for your environment.
