Resend a Misplaced Certificate

METHOD #1:

If your certificate recipients have access to the Portal, you can send them there to download a fresh copy of any issued certificate. They simply log in, click on their profile photo (or initials) on the top right of the portal, then click on Manage Account. One of the options that they'll see in the Account Settings area is Certificates. That page will show all of the issued certificates. Clicking on the 3 dots at the right side of any certificate will present a Preview option. From the Preview screen, they will see a download option.

METHOD #2:

As an administrator, you can access previously issued certificates by going into Portal & Groups (left navigation), then choose Certificates (top navigation). You can search by the recipients name to locate their certificate. You may need to adjust the time period because it shows the most recent 30 days by default. When you find the certificate, click the 3 little dots on the right of the row and choose Preview. You can copy/paste the url that is provided on that page and send the url to the recipient.

OTHER OPTIONS:

You can also drop a recipient into the original workflow that they went through to receive the certificate, if there aren't other things in that workflow that would be problematic to re-run. Alternatively, you could create a new workflow that has only one action which is to issue the certificate.  Note that reissuing a certificate will show an issuance date of the current date, so be mindful of that if the original issuance date is critical to maintain. If it is, then Method #2 above is preferable.
