How to Check When Your SSL Certificate Expires

There are several ways to check your SSL certificate's expiration date. You can click the padlock icon in your browser's address bar, use command-line tools like openssl, or use an online checker. But none of these methods will warn you when renewal time comes around.

1

Browser Method (Manual)

Click the padlock icon in your browser's address bar, then view the certificate details. This shows the expiry date but requires you to check every domain manually and regularly.

2

Command Line (Manual)

Use openssl s_client to connect to your server and inspect the certificate. Powerful but requires technical knowledge and is easy to forget.

3

Automated Monitoring (Recommended)

Sign up for Free SSL Tester, add your domain once, and let us check it automatically. We will show you the expiry date on your dashboard and alert you before it is time to renew.

Automated Monitoring vs Manual Checks

Manual certificate checks are fine for a one-off look, but they rely on you remembering to check again before the certificate expires. With automated monitoring, you add your domain once and Free SSL Tester does the rest.

Manual Checks

  • Easy to forget to check
  • Tedious with multiple domains
  • No alerts or notifications
  • No historical data

Automated Monitoring

  • Set it once and forget it
  • Monitor unlimited domains (Pro)
  • Email and webhook alerts
  • Full certificate history and status dashboard

Frequently Asked Questions

How do I check when my SSL certificate expires?

Sign up for Free SSL Tester and add your domain. Our tool will show you the exact expiration date, along with issuer details and certificate chain information. You can also check manually by clicking the padlock icon in your browser.

How often should I check my SSL certificate expiry date?

Rather than checking manually, use automated monitoring. Free SSL Tester checks your certificate daily (free plan) or hourly (Pro plan) and alerts you before it expires, so you never have to remember to check.

What happens if I forget to renew my SSL certificate?

If your SSL certificate expires, browsers will display security warnings to your visitors, which can drive away traffic and damage your reputation. Automated monitoring with Free SSL Tester ensures you are always notified well before expiry.
