None

No attestation mode - suitable for software-based key storage.

This attestation type indicates that no cryptographic attestation verification is required or available. It is typically used with software-based authenticators like AppPinAuthenticator that generate and store keys in software keystores rather than hardware security modules.

Characteristics:

• No hardware verification required

• Compatible with all device types

• Suitable for general-purpose applications

• Lower security assurance compared to hardware attestation

Example:

val authenticator = AppPinAuthenticator()
val result = authenticator.register(context, Attestation.None)
