Authentification

How to config the authentification.

The auth part is similar at the authjs documentation. You can follow the official documentation here if you want.

After upgrade Auth.js to v5: NEXTAUTH_URL has removed from .env file. Same thing in production.

Update auth_secret variable

The only environment variable that is mandatory is the AUTH_SECRET. This is a random value used by the library to encrypt tokens and email verification hashes. You can generate one via running:

npx auth secret

Alternatively, you can use the openssl CLI, openssl rand -base64 33.

Or this link for generate a random secret key.

Then add it to your .env file:

.env
AUTH_SECRET = secret;

GOOGLE_CLIENT_SECRET = your_secret_client;
