Unable to login to Unipass Mailock with a Unipass Identity

Why can’t I access a Unipass Mailock email with Unipass Identity?

There are 2 reasons why your Unipass Identity might not be working:

  • Is your certificate valid?

    • You have presented a revoked Unipass certificate:
      • A collected Unipass certificate might have been cancelled (or revoked) prior to its original expiry/valid to date, if it has been lost/compromised from your device.
    • You have presented an expired Unipass certificate:
      • An expired certificate is where the collection/renewal period for your Unipass certificate has been exceeded (e.g. you are trying to present a certificate that is now beyond the ‘valid to’ date).
  • You can test you certificate to see if it is working.

  • How can I test my Unipass certificate?
  • Who can I contact for further assistance/troubleshooting?
    • The contact details for the Unipass Mailock Helpdesk are as follows:
