I'm a little confused about your word "authenticate." You should be able to sign in to Google at google.com or gmail.com on whatever browser you have on your phone. If you really need to 2-step "Authenticate" something with Google, you need to get the "Google Authenticator" app on Google Play. https://forums.androidcentral.com/e...le.android.apps.authenticator2&token=S2ZDlm0- Many places will take Authy or Microsoft Authenticator. But do you really need 2-step authentication, or do you just need to sign in?
