Authentification – SaaS Starter

Docs

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.local

AUTH_SECRET = secret;

Update google client variables

In this section, you can update these variables:

.env.local

GOOGLE_CLIENT_ID = your_secret_client_id.apps.googleusercontent.com;
GOOGLE_CLIENT_SECRET = your_secret_client;
