What Hacker News says

It is claimed that MultiMC will not work unless you have authenticated it with active Microsoft account at least once on a computer, even if you only want to use it in offline mode: https://github.com/MultiMC/Launcher/issues/4433#issuecomment... This is probably related to the fact that MultiMC dev allegedly works for MS now. So even if you paid your hard-earned $30 for Minecraft back in the day, now you apparently also have to pay Microsoft the PII tax in the form of an active phone number. (Microsoft mines phone numbers via the shady practice of letting anyone quickly migrate their Mojang account, and then within weeks alleging suspicious activity violating ToS. Once it happens, you get a screen that offers none of your previously configured 2FA methods, such as backup codes or TOTP app, requiring you to receive a PIN via SMS. In the en

d, players submit their numbers voluntarily, because the alternative is to spend hours upon hours bickering with tech support without clear guarantee of success. Upon gaining access and inspecting this 'suspicious activity' players appear to inevitably find it to consist exclusively of their own logins from the same home IP they always use.)
In Thanks Microsoft for taking away one of my simple pleasures (Minecraft)
I have done some poking around and digging into the microsoft account lock out thing, out of curiousity- only to find it appears to be true, as i've had a LOT of test accounts banned in the past 2 months. I was trying things like setting up alternate emails, and TOTP... I suspect burner phones are the only way to not give one's phone number, or to gamble with the microsoft authentication app, which theoretically ever since recent versions of android should not be able to pull your phone number from the hardware - theoretically. I have not tested that out yet. There's quite a bit about this out there Here's one such thread where a lot are trying to figure out why they are being forced to give up their number https://github.com/MultiMC/Launcher/issues/4093 to my understanding, since they fully linked it- once your MS account auto locks- yo

u can't do anything, since it's linked to Minecraft- as well as other stuff. You'd think they'd allow one to still play Minecraft- but i guess if you can't log into the account, you're out of luck

Can Minecraft be played without giving MS a Phone#?

Microsoft is due to start forcing every single account on Minecraft to a Microsoft if it isn't already, over the next 2 days, I have read. I have learned that if you make a Microsoft account, their system auto-locks you out and forces you to provide them a phone number I play with my family (it's something we've bonded together over a long time) and we take our privacy seriously, and don't give up our phone numbers to companies , frequently using burner apps or other methods to set up stuff. However, Microsoft accounts don't accept VOIP numbers it seems, and their official guidance is to find someone near you if you don't have a phone, and use their phone to validate your account. This seems like a huge risk to someone else, with Microsoft now having their number (there's nothing that indicates they don't keep it.) Also, if this is for sp

am prevention, then if you have a lot of kids, you would be in trouble due to multiple accounts sharing the same number unless you bought every kid a phone. Apparently alternate email addresses used to be enough, to stop this but the system still automatically flags you. I don't know if TOTP 2 factor authentication works, but have read if you submit the reclaim-your-account form with lots of personal details, Microsoft considers this not-workable if you had setup MFA on your account and won't intervene. An option with Microsoft accounts is to set up their own dedicated microsoft authentication app to get in passwordlessly (but that feature isn't going to be on the Minecraft launcher, likely) , but this isn't as clear cut over if it pulls your phone number and other details from your phone. Does anyone know of a method my family could preserve their phone number privacy while continuing to play? Is there a way to set up a Microsoft account with enough authentication that it doesn't auto-ban you a little bit later and force you to give them more info to keep the account? I don't know if TOTP is enough, there's been mixed results per https://github.com/MultiMC/Launcher/issues/4093 I know some might wonder about third party clients or as some called them it seems ,hacked clients , but those don't support LAN/multiplayer it appears. Note: the message Microsoft accounts tell you is that they detected suspicious activity, but for those who gave them the info then checked the suspicious activity log in the (new)account, nothing but their own logins are shown, indicating this might be more of a phone-number-obtaining thing. I have trouble believing the tens of millions of players on Minecraft are all able to give phone numbers, and this seems concerning from a privacy point of view.

The dark of it clears when looking at the licensing of the open source launcher MultiMC: https://github.com/MultiMC/Launcher <quote> We keep MultiMC open source because we think it's important to be able to see the source code for a project like this, and we do so using the Microsoft Permissive License (MS-PL). The license gives you access to the source MultiMC is built from, but: - Not the name, logo and other branding. - Not the API tokens required to talk to services the launcher depends on. - You may not change the license. Because of the nature of the agreements required to interact with the Microsoft identity platform, it's impossible for us to continue allowing everyone to build the code as 'MultiMC'. The source code has been debranded and now builds as DevLauncher by default. You must provide your own branding if you want to distr

In Java Edition is moving house
Also mass locking Microsoft accounts that were created without providing a phone number[1]. For some reason they locked my completely unused Microsoft account, that was created for the sole purpose of migrating my Minecraft account to, due to "unusual behavior" (or "activity that violates our Microsoft Services Agreement" if you go by the error message instead of the corresponding knowledge base article). The reasonable thing to do in such a case if of course to require users to "[verify] [they] are the account owner" by receiving an SMS verification code on an arbitrary phone number (they explicitly mention the possibility of "asking a trusted friend or family member" for this).
