If you run a website that send browser push notifications, you have most likely received this email from Apple reminding you that your push certificate for Safari is about to expire. I’ve been receiving the same email for several years now, but every time I scratch my head wondering how do I do that again.

So this year, I decided to write down the steps and publish them for everyone (but mostly me) to follow again in the future when it’s time to renew the Safari push certificate.

How to renew a Safari Website Push Certificate

In order to generate a new Safari Website Push Certificate, you will need a paid developer account. First you will have to request a certificate from a certificate authority using Keychain Access on your Mac, then you will need to create a Web Push Certificate. We’ll walk you through each step with simple instructions and illustrations.

Note that the following instructions are to generate a Safari push certificate for a website that is already registered to send push notifications. If your website is not registered yet, make sure to login to your Developer account, click on Identifiers  and then click on Register an App ID. Then select Website Push IDs and click Continue. Type in a description, an identifier, and then click Continue to finalize the registration. Once done, you may go on with the instructions below.

1) First we need to make a certificate signing request. Open Keychain Access on your Mac, then navigate to Keychain Access > Certificate Assistant > Request a Certificate From a Certificate Authority…
