Every certificate has a QR code and a check link. Anyone can use either to see the certificate is genuine, without signing in.
To share one certificate, open it and press "Share this certificate". Copy the check link and send it, or press "See what they will see" first.
To put a certificate on your LinkedIn profile, open it and press "Add to LinkedIn". LinkedIn opens its form for adding a certification. Check the course name, that Creative Education is the issuer and the date, add the check link from your certificate so anyone can see it's genuine, and save. "Share on LinkedIn" posts it to your feed instead. The certificate email has an "Add to LinkedIn" link too.
To share your whole record (for an interview, a new school or an appraisal), go to Your record and press "Share record". Choose when the link stops working, then copy it. You'll see how many times it's been opened, and you can press "Turn off" whenever you like.
For an appraisal, "Appraisal pack" gives you a printable summary of your training, CPD hours and reflections.
