National Authentication Service for Health

Healthcare providers and supporting organisations use the National Authentication Service for Health (NASH) to securely access and share health information.

NASH Public Key Infrastructure (PKI) certificates help you to:

  • access My Health Records
  • securely share health information using software that meets secure message delivery requirements
  • access the NASH directory on the Certificates Australia website.


You're eligible for a NASH PKI certificate if your organisation is registered in the Healthcare Identifiers (HI) Service. Your organisation can either be:

  • a healthcare provider organisation
  • a contracted service provider
  • a general supporting organisation that assists in the delivery of digital health.
