Auth0 login on android device without web browser

Hi!

I’m developping an native android app used by employees of a company only, the app is not public. And they are supposed to use their google work account to log in. The issue is that the app should run on a all-in-one bank terminal running on android, and for security concern, the device doesn’t have any web browser (and can’t be installed). Is it possible to run the universal login in a webview rather than an external browser? Should I use legacy embedded solutions like Lock.Android instead?

Thanks for the help!
