It looks like AccelByte only supports OIDC logins right now. Is there any way to build a custom login flow using WebAuthn? Basically the idea is that client devices store private keys, and sign a challenge from a server using that private key to verify the client device. This is a superior login method to OIDC because it doesn’t rely on a centralized service like Facebook or Microsoft; it only relies on the client device’s ability to safely store keypairs.
Apple added support for WebAuthn in the latest iOS, and refers to them as ‘Apple Passkeys’.
