 ## Authentication
 
-!!! NOT REQUIRED ANYMORE !!!
-Microsoft has made the chat feature available to everyone, so you don't need to use cookies from a logged-in Microsoft account any more.  However, if you wish to cycle through multiple cookies/accounts, please look at the `EdgeUtils.Cookie` methods.
+!!! POSSIBLY NOT REQUIRED ANYMORE !!!
+In some regions, Microsoft has made the chat feature available to everyone, so you might be able to skip this step. You can check this with a browser (with user-agent set to reflect Edge), by trying to start a chat without logging in.
+
+It was also found that it might depend on your IP address. For example, if you try to access the chat features from an IP that is known to belong to a datacenter range (vServers, root servers, VPN, common proxies, ...), you might be required to log in while being able to access the features just fine from your home IP address. If you receive the following error, you can try providing a cookie and see if it works then:
+`Exception: Authentication failed. You have not been accepted into the beta.`
