I am using 2.3 beta, and I use the Sign in using browser method:

Even though I am already signed in, the basemaps are not all loaded and I have to sign in again multiple times to load each basemaps :

The sign in prompt appears every 2 minutes or so, and opens a new tab in my browser each time :

Thank you.
Thanks for your feedback. Please check if there are any inaccessible basemaps in your basemap gallery. The login prompt is probably triggered when loading the thumbnail. We encountered a similar issue when searching for public portal items from ArcGIS Online after signing in. We have a fix for this problem that might resolve your issue in the upcoming release.
Best,
