How to enable multiplayer on an account from family settings

I created a second account on family settings but can't log into it. Could someone please help me

Hope you're doing great today Jake

If you already have all your privacy settings enabled:

Minecraft Java Edition requires an extra config to play as usual multiplayer.

According to official FAQ:
"The minimum age for a standard account is thirteen. Children under that age need parental consent to access specific features, as required by law. To give parental consent to access these features, including Realms, you must enter payment information, which must be validated with a 10-cent charge. Currently, this is the only method to limit permissions for a child’s account on Minecraft Java."

That should do the trick on the child account.

I am sorry to hear that.

Please verify if your multiplayer settings is enabled on your account.

You can enable the multiplayer for Minecraft from the Xbox Family Settings app on your mobile device.

In the Xbox Family Settings app:

Go to Settings > In Enable Minecraft > Select Allow this game.

Turn on Multiplayer to let a member play online with others

Enable Clubs so that a member can create and join Minecraft Realms servers.

To download the Family App: https://www.xbox.com/apps/family-settings-app

I hope this helps.

Is there a family settings enabled? Try disabling it from the Settings, Account and then Family settings

Thanks for finding the page.

I wonder how this plays into the following:

FAMILY GROUP MULTIPLAYER FEATURES

3. If Minecraft is rated above a member's age limit, enable Allow gameplay under Enable Minecraft to grant the member and exception to play it.

• Enable Multiplayer to let a member play Minecraft with others online, even if their account settings block them from multiplayer features.
  

We've set the multiplayer as "allow", and the page says this should override age restrictions, but multiplayer just remains grayed out and when hovering over it it tells us to check our microsoft account settings... which we have.

Sorry this issue is such a mess.
