import os from certbot_dns_duckdns._internal.dns_duckdns import DuckDNSAuthenticator token = os.environ.get('DUCKDNS_TOKEN', '') auth = DuckDNSAuthenticator(token) # Use with certbot: certbot certonly --authenticator certbot-dns-duckdns:duckdns --certbot-dns-duckdns:duckdns-credentials /path/to/credentials.ini

Known issues
breakingcertbot-dns-duckdns v1.7.0 dropped support for Python 3.9 and switched from python-certbot to the internal certbot API. Older versions (<=1.6) are incompatible with certbot 5+.
fix
Upgrade to latest certbot-dns-duckdns and ensure Python >=3.10.
affects: >=1.7.0
gotchaThe plugin's entry point name is 'duckdns', not 'certbot-dns-duckdns'. Use --authenticator certbot-dns-duckdns:duckdns.
fix
Refer to the CLI as certbot-dns-duckdns:duckdns.
affects: all
gotchaDuckDNS token must be set in the credentials file or as environment variable DUCKDNS_TOKEN. If using the file, ensure permissions are strict (600).
