Hi everyone,
I’m working on adapting our app to iOS 26’s new passkey feature, specifically Automatic Passkey Upgrades. https://developer.apple.com/videos/play/wwdc2025/279/
Our app already supports passkey registration and authentication, which have been running reliably in production. We’d like to extend passkey coverage to more users.
According to the WWDC session, adding the parameter requestStyle: .conditional to createCredentialRegistrationRequest should allow the system to seamlessly upgrade an account with a passkey. However, in my testing, I consistently receive the following error:
Error | Error Domain=com.apple.AuthenticationServices.AuthorizationError Code=1001 "(null)"
Test environment:
- Xcode 26.0 beta 4 (17A5285i)
- iPhone 11 running iOS 26.0 (23A5297n)
Questions:
- Is the Automatic Passkey Upgrades feature currently available in iOS 26?
- I understand that the system may perform internal checks and not all upgrade attempts will succeed. However, during development, is there a way to obtain more diagnostic information? At the moment, it’s unclear whether the failure is due to internal validation or an issue with my code or environment.
Thanks.
