Your course list in, signed certificates out.

Paste your learners from a spreadsheet or your course platform: the name on the certificate, their e-mail, the course, and a number and expiry where it has them. Every certificate is signed as you issue it.

Your learners keep it, and grow it.

They claim it with a code e-mailed to the address you sent, so a forwarded link claims nothing. It lands on a free passport of their own. Their identity reads “not verified” until they check it, in plain words, so nobody is misled.

Checked in seconds, without asking you.

Each certificate has its own address and QR code. An employer sees the certificate, its number and expiry, and that you issued it, and checks the signature without e-mailing you.

Your name, in every application.

Wherever a learner applies with their passport, your certificate travels with your name on it: on the passport, on the certificate’s own page, and on their PDF CV once they subscribe.

In writingWhat a free certificate never does
  • Signs more than you issued. Nothing else borrows its verdict.
  • Implies identity. Unchecked reads unchecked.
  • Changes the name you gave. It stays as issued.
