"Error 403: disallowed_useragent" When Signing in in Tableau Mobile

Issue

When signing in in the Tableau Mobile app, the following error may occur:

Error 403: disallowed_useragent
You can’t sign in from this screen because this app doesn’t comply with Google’s secure browsers policy. If this app has a website, you can open a web browser and try signing in from there.
You can let the app developer know that this app doesn’t comply with Google’s secure browsers policy.

Environment

Tableau Mobile
Tableau Server
Tableau Cloud

Resolution

Tableau Server (version 2019.4 or later)

If deploying Tableau Mobile using an MDM or MAM system, set the AppConfig parameter RequireSignInWithDeviceBrowser to true. Alternatively, Tableau Server users can enable the "Sign in with Device Browser" setting on their individual devices. The AppConfig parameter overrides the user setting.

Tableau Cloud

Enable 'Sign in with Device Browser' by setting the AppConfig parameter RequireSignInWithDeviceBrowser to true when deploy the Tableau Mobile app with an MDM or MAM system. Note: The user setting has no effect for Tableau Cloud, so if you don’t use an MDM or MAM system, users won’t be able to use Google authentication with the app. A possible workaround would be to configure the users to use the default Tableau authentication method.
