To use the Google Pay app, you must sign in to a personal Google Account that wasn't created for work or another organization.
At this time, the new Google Pay app doesn't support Google Enterprise accounts, Google Workspace (previously G suite) accounts, or Android work profiles.
Change Google Account
On your phone, only one Google Account can be logged into the Google Pay app at a time.
To switch Google Accounts, sign out through the app settings and sign back in with a different Google Account.
Important: Some settings may be lost when you sign out of your account.
