Can Corvid be used to pass SSO information to third-party systems?

I frequently use Wix to build sites for clients, but on this occasion our client wants visitors to be able to sign in with a 5-digit authentication code and then navigate from our platform to a third-party platform without having to sign in again, ie with their name and authentication data being transferred to the third party system. JSON with SHA-256 signature then payload encoded with classical Base64. Does anyone know whether enabling Corvid will allow us to do this? Alternatively, is there a freelancer out there who would be able to help us implement this aspect?
