My site has a padlock. Am I done?
Check that http addresses redirect to https and that no images load over http, which triggers a "mixed content" warning.
What is SSL certificate (HTTPS)?
An SSL/TLS certificate encrypts traffic between a visitor and a website so the address shows https and a padlock; browsers flag sites without one as "Not secure".
Certificates expire, typically every 90 days for free Let's Encrypt certificates, and an expired one blocks visitors with a full-page warning. Modern hosts such as Vercel renew them automatically; older shared hosting often does not.
SSL is included and auto-renewed on every Studio 17 care plan, and we check it as part of the free website health check.
