HOW TO
In ArcGIS Pro version 2.7.2, it is possible to sign in to an ArcGIS Online or ArcGIS Enterprise account using a web browser instead of the built-in sign in dialog, if the organization uses built-in or SAML-based authentication.
A registry key can be set to redirect sign in workflows to a web browser automatically. To sign in to an ArcGIS Enterprise portal version 10.8.1 or earlier using this method, portal administrators must register a redirect URI for ArcGIS Pro with the portal.
Note: Users blocking Chromium or using sign in strategies not supported by the built-in sign in dialog may need to implement this strategy to sign in to portal through ArcGIS Pro.
Set ArcGIS Pro to sign in using a browser.
Windows 10: HKEY_CURRENT_USER\Software\ESRI\ArcGIS Online For Pro\SignIn
Windows 11: HKEY_USERS\youruserprofileID\Software\Esri\ArcGIS Online For Pro\SignIn
Note: Steps 4 and 5 are necessary for Windows 10 users only. Windows 11 users can proceed to step 6.
Note: To disable, set the key Value data to 0, or remove the key.
Note: Step 8 is necessary for deployments configured with ArcGIS Enterprise. No further configuration is required for ArcGIS Online connections.

{ "appId":"arcgispro", "redirectURIs":["urn:ietf:wg:oauth:2.0:oob","arcgis-pro://auth/"] }
Note: If the portal is configured with Named User licenses for ArcGIS Pro, the redirect URI must also be registered for app ID arcgisprodesktop.
Note: The option to sign in using a browser is expected to be supported directly from the interface in ArcGIS Pro 2.8.
