Your SSL Certificate Is Changing in 2026. Your Website Is Going to Be Fine.

If you’ve seen something about SSL certificates changing in 2026 and wondered whether your website is affected, you are in the right place. The short answer is that if Midphase manages your hosting, your site won’t be disrupted and you don’t need to do anything. The longer answer is worth understanding, because this change is going to keep coming up.

Let’s start with the part that matters most

No, your website is not going to go down.

Because a certificate can now only be valid for 200 days, it needs to be reissued once within your annual subscription period. We handle that automatically. Your site stays live, your certificate stays active, and you won’t notice it happened.

Your subscription isn’t changing either. Annual billing, same renewal date, same terms. The only thing different is a background process we run mid-term that didn’t exist before.

So what actually changed – and why?

SSL certificates are what put the padlock in your browser bar. They tell visitors your site is secure and that their connection to it is private. Every website needs one, and they have an expiry date.

Until now, a certificate could be valid for up to 398 days – just over a year. From March 15, 2026, that maximum drops to 200 days. It’s an industry-wide rule change approved by every major browser: Apple, Google, Mozilla, and Microsoft all voted for it. It applies to every website, everywhere – not just Midphase customers.

The reason is straightforward. A certificate that runs for 398 days can go 398 days without anyone checking that the business behind it still legitimately owns the domain. Shorter certificates mean more frequent checks. More frequent checks mean a more trustworthy web.

One thing worth doing today

You might get an automated email from the certificate issuer at some point, sent to your domain’s admin contact address. It’s just a confirmation that the reissue ran – you almost certainly don’t need to do anything. But it’s worth making sure that email address is one you actually check.

Log into your control panel, find your domain settings, and confirm the address is current. Thirty seconds now saves confusion later.
