Questions from passkey integration projects
See what others have asked about integrating passkeys:
#11 Can passkeys be created and used within iframes?
Yes, passkeys can typically be used within iframes for login, but certain browsers (e.g., Safari on iOS and macOS) restrict creating passkeys directly within iframes. In these cases, an initial redirect outside the iframe is necessary to create the passkey, after which login can resume seamlessly inside the iframe.
No more vendor lock-in: passkeys are becoming portable
Until now, migrating passkeys from one provider to another - say, from iCloud Keychain to Bitwarden - was impossible. There just wasn’t a secure or standardized way to do it. This blog introduces two new FIDO-backed specs that could change that: the Credential Exchange Protocol (CXP) and Credential Exchange Format (CXF). Together, they define how passkeys can be safely transferred across platforms using encryption and manifest files. Plus, it’s not just for passkeys. This could also cover payment data, TOTP codes and digital IDs in the future.
But how exactly does the exchange process work and when will it be ready for real-world use?
