Configure automatic login + sync in Edge with intune
Signing in to the browser does not mean that synchronization is enabled by default; the user must sign in separately to use this feature. (1)
If you set this policy to "Enforce login to browser" (2), users must login to a profile to use the browser. By default, this allows the user to choose whether they want to sync with their account. (2)
If you do not configure this policy, users can decide whether to enable the login option with the browser and use it as they see fit.
0 = Disable browser sign-in
1 = Enable browser sign-in
2 = force users to log into Edge
