Setting Power BI to use a default web browser has resolved the login issue for users who raised support ticket. We recommend this as the standard configuration going forward. In Power BI, go to File > Options And Settings > Options > Security > Scroll down to "Authentication Browser" > Enable "Use my default browser".

Update
Dave4564 on the community shared a workaround for those folks not getting the login box or being unable to delete old credentials: In Power BI, go to File > Options And Settings > Options > Security > Scroll down to "Authentication Browser" > Enable "Use my default browser"
When you try to refresh the data now, the login should open up in a browser window and allow you to log in.

Investigating
We are investigating reports that in some cases the Power BI connector is no longer able to log in to retrieve reporting information.
