myGovID is a software application designed to be a centralised method of authentication for users of government websites and services in Australia.^[3] The app, developed by the Australian Taxation Office (ATO) and Digital Transformation Agency, first launched in October 2019, with a public beta being performed earlier that year in June.^[4] myGovID was created to unify the various authentication methods employed by departments across federal and local governments, most notably AUSKey.^[5] The app allows users to verify their identity using biometrics such as fingerprints or facial recognition.^[6]

As of January 2024, the MyGovID app has a 1.6 star rating on the Apple App Store and a 2.3 star rating on the Google Play Store.^[1][2] Common issues raised include a low standard for proof of identity, an ability to register multiple accounts under the same identity, a refusal to recognise government-issued IDs, an inability to change most details, and inadequate functionality.

On 1 April 2020, the ATO disabled its legacy AUSKey and "Manage ABN Connections" login methods in favour of myGovID. The subsequent traffic spike caused minor outages during the day.^[7]
