Frequently asked

What is Let's Encrypt?›
Let's Encrypt is a free, automated, and open certificate authority (CA) provided by the Internet Security Research Group (ISRG) that aims to make the process of acquiring SSL/TLS certificates easy and accessible for website owners, enabling a more secure internet experience for all users.
How does Let's Encrypt differ from other certificate authorities?›
Let's Encrypt is unique among CAs due to its focus on automation, cost-free certificates, and ease of use. The primary goal of the project is to lower the barriers to entry for SSL/TLS adoption by simplifying certificate issuance and renewal, making secure connections more widespread across the internet.
Are Let's Encrypt certificates compatible with all browsers and devices?›
Yes, Let's Encrypt certificates are widely supported and recognized by modern browsers and devices. The cross-signature provided by IdenTrust, a major certificate authority, ensures that the Let's Encrypt certificates work seamlessly with almost every device that connects to the internet.
How long is a Let's Encrypt certificate valid, and can it be renewed?›
Let's Encrypt certificates have a validity period of 90 days. They can and should be renewed automatically before they expire to maintain the secured connection. By using tools such as Certbot or other ACME clients, the renewal process can usually be automated, minimizing manual intervention.
Is it possible to obtain a wildcard certificate from Let's Encrypt?›
Yes, Let's Encrypt does provide wildcard certificates for securing multiple subdomains with a single certificate. To request a wildcard certificate, you need to use an ACME client that supports the required DNS-01 challenge, such as Certbot or another compatible ACME client.
