Set up SSL
There are two methods to support TLS/SSL in n8n.
Use a reverse proxy (recommended)
Use a reverse proxy like 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{: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 for more information on these variables and Configuration for more information on setting environment variables.
