Can't login to my customer page after whatever was changed recently. The normal 'my account' page gets stuck in an endless redirect loop, I'm not comfortable allowing unknown domains to run javascript unless somebody can give me a really good reason.
I understand your concern.
b2clogin is our new identity provider. We have decoupled our login authority from our website. This was necessary to allow you to use your same login credentials across some new sites and products we intended to release in the future.
I assume you're using NoScript. You can b2clogin.com as a trusted site.
I found that I also have to allow windows.net to eliminate the endless-looping, which isn't that easy to do since windows.net isn't in the Noscript list until it's between page redirects. Had to freeze it mid-load with the ESC key to find it.
So to log in I have to grant access to windows.net internet-wide? Man, I don't even allow Google to run JS or set cookies.
