| # Set up SSL | |
| There are two methods to support TLS/SSL in n8n. | |
| ## Use a reverse proxy (recommended) | |
| Use a reverse proxy like [Traefik](https://doc.traefik.io/traefik/){:target=_blank .external-link} or a Network Load Balancer (NLB) in front of the n8n instance. This should also take care of certificate renewals. | |
| Refer to [Security | Data encryption](https://n8n.io/legal/#security){:target=_blank .external-link} for more information. | |
| ## Pass certificates into n8n directly | |
| You can also choose to pass certificates into n8n directly. To do so, set the `N8N_SSL_CERT` and `N8N_SSL_KEY` environment variables to point to your generated certificate and key file. | |
| You'll need to make sure the certificate stays renewed and up to date. | |
| Refer to [Deployment environment variables](/hosting/configuration/environment-variables/deployment.md) for more information on these variables and [Configuration](/hosting/configuration/configuration-methods.md) for more information on setting environment variables. | |
