Issue with Blizzard battle.net Authenticator / Blizzard website.
Using Google Chrome 100.0.4896.127.
After logged in, it will ask to authorize in the authenticator and will return to the password screen immediately after authorizing.
Works on Firefox 99.0.1
I believe the problem here is that the web browser version reached version 100
