I have been using Google Family Link recently in order to keep my child’s mobile phone online while safeguarding it against mature content.
Sometimes I have logged in to the device using the parent access code and that has brought up a question that doesn’t seem to have great answers in the manual of this software: How does one logout from the child’s device after accessing it with the family link parent code?
Here’s the answer: in order to quit accessing the child’s device as a parent, go to the Google Family Link app on the parent’s device and right beneath the circular image on the top, there should be your child’s device listed. Click on the name of the device and click on “lock”. Now the device should only be available if there is screen time left and the time is withing the allowed time limits.
