How to Fix an “Auth check failure on device(s)” error on Google home

If you get an “Auth check failure on device(s)” error when you try to add a shared Google Assistant-enabled device, you’re not a member of the home that the device is linked to in the Google Home app.

2. Resolution

Join the home linked to the device

You can’t use the steps below to join a home with your Google Workspace account 

Step 1: Ask a member of the home to invite them

To join a home, ask a member of the home in the Google Home app to invite you.

To link a child’s account that’s managed in Family Link to a device, the parent in the child’s Google Family Group who’s trying to link their child’s account must join the home.

Step 2: (For Home members) Invite a member to their home

• If the person they want to invite has already sent a request to join your home, don’t send a new invitation.
• You can’t invite a child with an account managed with Family Link to home. After the parent joins the home, they can add their child’s account to the device.

As a home member, you can invite people to your home. A home can have up to 6 members.

1. Open the Google Home app

2. Switch to the home you want to share.
3. At the top, tap Add

3. To invite them, tap Add to Family.
4. To skip this step, tap No Thanks.
5. Note: You can have up to 6 members in a Google Family Group.

The person you invite should receive an email with instructions.

Step 3: Accept the home member invitation

Step 4: For a child’s account managed with Family Link only

To add a child’s account that’s managed in Family Link to a speaker or Smart Display, you must meet both of these requirements:

• Be a parent in the child’s Google Family Group.
• Be a member of the home the device is linked to in the Home app.

If you’re the parent in a Google Family Group and you want to link your child’s account that’s managed in Family Link to a speaker or Smart Display, you can do that after you’ve joined the home.
