Website health
How do I check when my SSL certificate expires?
Short answer: Click the padlock in your browser's address bar and view the certificate, or run a free website health check, which shows the expiry date and warns you when it is close.
The full answer
Certificates now last at most about a year, and many free ones last 90 days and renew automatically.
If yours is close to expiring and doesn't renew on its own, check your host's auto-renew setting or renew it manually.
