Windows 10 Pro, V 1909, Build 18363.535 Latest update Child only has a profile on one machine No, there is no “error”, instead I am returned to the login screen without explanation. However, there are various status message that flash past. They go too quick to read properly. I believe I see obtaining authentication token, then redirecting… I could be mistaken, it goes so far. Latest version of the entire suite, including password manager, safe browsing, but not VPN. Premium. What do you mean authenticated account? It has *authentication*, that is what is failing. It does not appear to use an OAuth 2 solution, such as Google Account login. It has its own authentication solution that is specific to Mojang; e.g. cannot use MS Password. As the account is new, it’s never been tested before. Essentially, I cannot answer this question meaningfully. It may be an old issue, but the account is new, so I only just tried it. Do you mean in Kaspersky, or in Mojang? I don’t believe Mojang apply any age limits to Minecraft. It is a child under 13 in KSK.
