badg.co used to be the website where recipients of Certify credentials logged in to see their badges and certificates. It is no longer in use.
Your credentials have not gone anywhere. Everything that was available on badg.co is now at app.certify.one.
How to find your credentials
Go to app.certify.one.
Log in with the email address your credentials were issued to. Your badg.co password may not work, so if it doesn't, use the forgotten password option to set a new one.
You will see all the credentials issued to that email address, each with a current link you can share.
If you shared an old badg.co link on LinkedIn, in your CV or elsewhere, replace it with the new link from your credential page.
