Plugins

Better Auth has a rich plugin ecosystem. Any Better Auth plugin can be used with this Strapi adapter. Some plugins add new database tables that Strapi needs to know about — these require a schema generation step.

Adding a plugin​

Enable plugins in your Better Auth config:

src/lib/auth.ts
import { betterAuth } from 'better-auth';
import { twoFactor } from 'better-auth/plugins';
import { strapiAdapter } from '@strapi-community/plugin-better-auth';

export const auth = betterAuth({
  database: strapiAdapter(),
  trustedOrigins: ['http://localhost:3000'],
  advanced: {
    database: {
      generateId: 'serial',
    },
  },
  plugins: [
    twoFactor(),
  ],
});

Schema generation​

Plugins that introduce new tables (e.g. two-factor, passkey, organization) require you to run Better Auth's generate CLI so Strapi picks up the new content types.

npx auth generate

After running the command, restart Strapi in development mode. The new content types will be registered automatically:

pnpm develop

Example: OAuth (Google)​

src/lib/auth.ts
import { betterAuth } from 'better-auth';
import { strapiAdapter } from '@strapi-community/plugin-better-auth';

export const auth = betterAuth({
  database: strapiAdapter(),
  trustedOrigins: ['http://localhost:3000'],
  advanced: {
    database: {
      generateId: 'serial',
    },
  },
  socialProviders: {
    google: {
      clientId: process.env.GOOGLE_CLIENT_ID!,
      clientSecret: process.env.GOOGLE_CLIENT_SECRET!,
    },
  },
});

Then in your front-end:

await authClient.signIn.social({
  provider: 'google',
  callbackURL: '/dashboard',
});
