Swift: Sign in with a passkey

Signs the user in with a passkey (WebAuthn). Available on iOS 16+, macOS 13+, and visionOS 1+.

• Drives the full WebAuthn ceremony end to end: fetches assertion options from the server, presents the native passkey UI via AuthenticationServices, and verifies the assertion.
• Does not require an existing session. On success the session is persisted and a signedIn auth change event is emitted.
• For lower-level control (custom authenticator, tvOS, watchOS), use getPasskeyAuthenticationOptions() + verifyPasskeyAuthentication() instead.
• Passkey support is experimental. Opt in with @_spi(Experimental) import Supabase. The API may change in future releases.
• Passkeys must be enabled for your project in the Dashboard under Authentication → Passkeys.

Examples

Sign in with a passkey

// iOS 16+/macOS 13+ only. Must opt in: @_spi(Experimental) import Supabase
let response = try await supabase.auth.signInWithPasskey(
  presentationAnchor: view.window!
)
let session = response.session
let user = response.user
