The authentication migration process came with some issues and forum was fed with feedback from the community.
Today, I’m not aware of any issue.
If you used your Google session to create your UiPath account, are you expecting google to share with UiPath both your email and your password (password that shouldn’t be stored in plain text or alike) or UiPath to grab them on the fly?
A nice addition would be to be able, from our forum account, to add other UiPath SSO authentication modes and manage them or to have a shortcut to this kind of management.
EDIT: by the way, you title is not accurate: you can only use google authentication
