## Topics

### Creating passkey credential requests

[`init(credentialIdentity:clientDataHash:userVerificationPreference:supportedAlgorithms:)`](/documentation/AuthenticationServices/ASPasskeyCredentialRequest/init(credentialIdentity:clientDataHash:userVerificationPreference:supportedAlgorithms:)-1jihy)

Initializes a passkey credential request, identifying supported algorithms by number.

[`init(credentialIdentity:clientDataHash:userVerificationPreference:supportedAlgorithms:)`](/documentation/AuthenticationServices/ASPasskeyCredentialRequest/init(credentialIdentity:clientDataHash:userVerificationPreference:supportedAlgorithms:)-52txr)

Initializes a passkey credential request, identifying supported algorithms with constants.

[`initWithCredentialIdentity:clientDataHash:userVerificationPreference:supportedAlgorithms:`](/documentation/AuthenticationServices/ASPasskeyCredentialRequest/initWithCredentialIdentity:clientDataHash:userVerificationPreference:supportedAlgorithms:)

Initializes a passkey credential request.

[`init(credentialIdentity:clientDataHash:userVerificationPreference:supportedAlgorithms:extensionInput:)`](/documentation/AuthenticationServices/ASPasskeyCredentialRequest/init(credentialIdentity:clientDataHash:userVerificationPreference:supportedAlgorithms:extensionInput:)-9hsyv)

Initializes a passkey credential request, providing additional passkey assertion data.

[`init(credentialIdentity:clientDataHash:userVerificationPreference:supportedAlgorithms:extensionInput:)`](/documentation/AuthenticationServices/ASPasskeyCredentialRequest/init(credentialIdentity:clientDataHash:userVerificationPreference:supportedAlgorithms:extensionInput:)-1258o)

Initializes a passkey credential request, providing additional passkey registration data.

[`initWithCredentialIdentity:clientDataHash:userVerificationPreference:supportedAlgorithms:assertionExtensionInput:`](/documentation/AuthenticationServices/ASPasskeyCredentialRequest/initWithCredentialIdentity:clientDataHash:userVerificationPreference:supportedAlgorithms:assertionExtensionInput:)

Initializes a passkey credential request, providing additional passkey registration data.

[`initWithCredentialIdentity:clientDataHash:userVerificationPreference:supportedAlgorithms:registrationExtensionInput:`](/documentation/AuthenticationServices/ASPasskeyCredentialRequest/initWithCredentialIdentity:clientDataHash:userVerificationPreference:supportedAlgorithms:registrationExtensionInput:)

Initializes a passkey credential request, providing additional passkey registration data.

### Viewing passkey challenge information

[`clientDataHash`](/documentation/AuthenticationServices/ASPasskeyCredentialRequest/clientDataHash)

The hash of the client data for this assertion.

[`userVerificationPreference`](/documentation/AuthenticationServices/ASPasskeyCredentialRequest/userVerificationPreference)

The relying party’s user verification preference.

[`supportedAlgorithms`](/documentation/AuthenticationServices/ASPasskeyCredentialRequest/supportedAlgorithms-74mad)

A list of cryptographic signature algorithms that the relying party supports.

[`supportedAlgorithms`](/documentation/AuthenticationServices/ASPasskeyCredentialRequest/supportedAlgorithms-27z68)

A list of cryptographic signature algorithms that the relying party supports.

[`extensionInput`](/documentation/AuthenticationServices/ASPasskeyCredentialRequest/extensionInput)

An input for WebAuthn extensions.

[`ASPasskeyCredentialExtensionInput`](/documentation/AuthenticationServices/ASPasskeyCredentialExtensionInput)

A type for WebAuthn extension inputs.

[`assertionExtensionInput`](/documentation/AuthenticationServices/ASPasskeyCredentialRequest/assertionExtensionInput)

An input for WebAuthn extensions.

[`ASPasskeyAssertionCredentialExtensionInput`](/documentation/AuthenticationServices/ASPasskeyAssertionCredentialExtensionInput-c.class)

A type that encapsulates input for various WebAuthn extensions during passkey assertion.
