Auth.js is the Next-native OSS path. Same deal: you own providers, the database adapter, and email. AUTH_SECRET plus OAuth client IDs. Fine if the scaffold is already NextAuth — do not migrate to Clerk “because the blog said so” mid-demo. - Source: dev.to / 4 days ago
I use libraries for authentication rather than building it myself. For Memoreru, I chose Better Auth. Auth.js is also an option. - Source: dev.to / 10 months ago
