myID, formerly myGovID, is a software application designed to be a centralised method of authentication for users of government websites and services in Australia.

[3] The myGovID 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.

[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.

[citation needed] On 1 April 2020, the ATO disabled its legacy AUSKey and "Manage ABN Connections" login methods in favour of myGovID.
