# HTTP Auth

### HTTP01 Auth

This is the default Certbot authentication method and only works if your web server is exposed on a public IP address with ports 80 and 443 open.

This is the simplest auth provider and requires no configuration. If you are running a public web server then you should use this version.

HTTP01 Auth does not support wildcard certificates.

If you are using docker-compose or creating your own container then you need to set the following environment variable when you are creating the container.

Set the following environment variables:

AUTH\_PROVIDER=HTTP01Auth

DOMAIN\_WILDCARD=false
