AUSkey is essentially a login that identifies an individual when they use participating government online services, on behalf of a business.
myGovID is the Australian government's digital identity credential -- handled by the ATO. It's like the 100 point ID check but on a smart device, and it allows citizens to have their identity verified so they can access government services using that verified identity, rather than being verified continually by each Commonwealth entity.
It became available as an app through the Apple and Google Play stores after it was quietly released in Apple's app store in June while the Android version was released in October.
A myGovID will need to be created before accessing ATO services.
"If you haven't already, the best time to get your myGovID is now," the ATO wrote.
To prove an identity on myGovID, individuals need to enter their full name, date of birth, and email address. Also required is two of either: an Australian passport, a state or territory-issued driver's licence, birth certificate, or Medicare card.
"If you are the principal authority for your practice, you can use your myGovID to login into the Relationship Authorisation Manager (RAM) website and link your myGovID to your practice Australian business number (ABN)," the ATO added of its new process.
"This will allow you to establish access permissions for your practice.
"Principal authorities will need to ensure all staff that need access to online services for agents have set up their personal myGovID."
Speaking previously on replacing AUSkey with myGovID, Digital Transformation Agency Assistant Secretary for Digital Identity and myGov Jonathon Thorpe said the concerns individuals have with being verified by government extend to organisations, too.
"It's a PKI credential, it's been around for a very long time," he said in August.
"What we found, apart from some UX irritants, was a whole bunch of fraud-related issues that were happening,
"The way it works at the moment is that you authenticate as an organisation, seldom do we know who is behind it."
According to Thorpe, it is the strongest identity proofing that can digitally be performed at the moment.
