What is Family Link?
Family Link lets you create a Google Account for your child that's like your account, while also helping you set certain digital ground rules for your family.
Family Link On CloudReady
"Family Link" is mediated by a protected API endpoint that only official Google builds could use similar to "Supervised Users" a similar feature that Google retired. Due to the "protected API" restriction, CloudReady does not support it at the moment.
As always when and if this feature becomes available for us to incorporate in CloudReady we will work on it and make it available for our users.
