Passkey authentication on the t3 stack using turso and upstash

T3 App Template with passkeys

This is a T3 Stack project bootstrapped with create-t3-app. I’ve hacked on Passkey/FIDO2/WebAuthn authentication.

Passkeys + NextAuth

I’m using a Next Auth Credential provider to authenticate the passkey credentials. This depends on simplewebauthn. It has the email provider as a fallback, but you could use something else.

JWT Sessions

NextAuth does not allow you to use Database sessions with the CredentialProvider, as far as I can tell. This is not well documented. It simply fails silently if you do. So I’ve added configuration to use a JWT session and get the user ID from the JWT.

Turso

I’m using Turso. For the database, largely because of their extremely generous free tier, but you can just swap it out for whatever making the appropriate changes to the prisma configuration.
