Minecraft is telling me that my parent or guardian has not provided me access to online...

Hi and thanks for reaching out. I hope you’re doing well. I'm an Independent Advisor and a Microsoft user like you and I'll be happy to help you.

That means the system is detecting that you're using a child account but if you're not on a child account, you can try changing your Privacy Settings at https://account.xbox.com/en-us/Profile?xr=mebar... but if it's redirecting you to a Support page, that means you are really using a child account.

In that case, you need to use an adult (organizer) account from your Family Group to change your Privacy Settings on the same link. Make sure that all settings under the Privacy tab and Xbox One/Windows 10 Online Safety are set to "Allow" or "Everyone". It should be like the screenshot below;

Also, make sure to set these settings to "Allow" or "Everyone".

- You can see and upload community creations

- You can communicate outside of Xbox Live with voice & text

- Others can communicate with voice, text, or invites

Additionally, if you're playing on an Xbox console, make sure you have an active Xbox Live Gold or Game Pass Ultimate.

Thanks for replying so quickly Darhyl! Unfortunately I can't log in at all. When I try, after entering my password, it come back to the screen that says this:

Based on the information provided, a parent or guardian needs to help finish setting up this account.

I’m a parent or guardian

I’ll sign in with my Microsoft account and give consent.

I’m not a parent or guardian

I need to ask a parent or guardian for help.

I click on the top one and it takes me through the process again, only to come back to this message again. It seems that somehow it isn't recognising me as the parent.

Well my problem is I’ve never needed a parent/guardian sign in (until recently for some reason), and if the DOB on the account can’t be changed, the Xbox considered my account a parent account when trying to get a parent/guardian sign in.

When I do sign in using the same account on the parent/guardian screen it just puts me back to the password screen.

The console itself could have parental controls enabled to prevent you from playing online that your PC does not have. Your parent or guardian would have to modify the account settings for the Child account to allow online gameplay. Verify with your parent
or guardian that they have enabled online gameplay on your account, or if they will allow it.

Yeah, I've looked at the suggestions, but none of them are working unfortunately. I've also been getting a different message when trying to accept the T&C on the website rather than the console, which tells me that a parent/guardian needs to create their
own XBL account. Not sure if I'm able to get my parents to do that, though...
