To access your Google Nest devices, you’ll need to sign in with your Google or Nest credentials.
Certified Google partners may ask you to access their service using the partner’s sign-in or Google account credentials.
Sharing your account email and password with unauthorized websites or apps can compromise the security of your home and personal information and no Hey Google partner will ever need your Google password. Be careful of websites or apps that may try to steal your account email and password by posing as a “Works with Google Assistant,” “Works with Google Home (formerly Works with Hey Google),” or “Works with Nest” partner.
Google Partner Security
Some companies are partnered with Google to integrate with Nest products through Google Assistant with the Smart Home API and Device Access Program/API. The Device Access Program is built on a foundation of privacy and security and gives our users the confidence that our partners offering integrated Nest solutions have the right data protections and safeguards in place that meet our privacy and security standards.
Companies that do not have certified Works with Google Home (or legacy Works with Nest) integrations, such as Starling, may also ask you to use your Google account information to sign into their service. When you enable an integration with a company that is not part of the Works with Google Home program, the safeguards we would otherwise have in place cannot be used and there is a risk of exposing sensitive data to inadequate data protection, privacy, and security standards. You may even expose yourself and others to additional safety risks by using functionality in ways it wasn't intended. There may also be additional consequences to unapproved integrations, based on violations of Google’s Terms of Service, such as a limitation in support or warranty coverage for Google products.
What to do if you start experiencing issues after sharing your account information
If you’ve already shared your email address and password with an unauthorized integration, you might experience one or more of the following:
- Uninvited people, websites, or apps could access your home and take control of your Nest products.
- Your products may behave erratically.
- The Nest or Google Home app may not work as it should.
- Nest’s 2-step verification may not work properly. In addition, you may get a series of unexpected text messages on your phone when the third-party service tries to use your information to sign in.
- You may receive unsolicited emails.
You might want to contact the third-party company and have them remove your information from their system. Google does not have access to the systems managed by third-party companies. You’ll need to contact the third-party company directly.
In some cases, you may not be able to remove your account information from third-party systems. However, you can always change your account password.
