Thank you for joining us at Alfred Center!
Here are the steps you can take:
Change your Gmail password. This revokes the access any individual might have to your Alfred Cameras.
Log in to your devices with the new password and enable Passcode Lock. This ensures nobody will be able to get to your Camera and turn it into a Viewer.
If you want someone to be able to watch live feed and Motion Events without being able to change anything about your devices, you can add her to your Trust Circle.
Please give these a go and let me know if it helps!
