Frequently Asked Questions

Let's Encrypt certificates are valid for 90 days. This short validity period is by design to encourage automated renewal and reduce the risk of key compromise. Most users set up cron jobs or use Certbot for automatic renewal.
HTTP-01 validates domain control by serving a specific file on your web server. DNS-01 validation uses a TXT record in your DNS zone and is required for wildcard certificates. DNS-01 works even when your web server is offline.
