For managed ChromeOS devices.
By default, users can sign in to multiple Google Accounts at the same time on a ChromeOS device. Users can switch between accounts without signing out and in again.
As a Chrome admin, you can control if and how multiple users can sign in to a device.
- You can block any managed account from becoming a secondary account (recommended).
- You can specify that the first user must sign in to a managed Google Account.
- The first user to sign in is the primary user. Subsequent users are secondary users. The data in each user account is kept separate.
- Most device-level settings that you set using the Google Admin console apply to all users on a device, even if they sign in as a guest or with a personal Google Account. However, certain settings do not apply to user sessions if they affect user privacy.
- Most user-level policies are individually applied to each account on a device. However, if a primary user signs in to a managed Google Account some of the Chromium policies that you set also apply to secondary accounts on the device. For a complete list of these policies go to the Chromium policy list and search for policies with Per Profile: No. See the Policy List.
On a ChromeOS device, the primary user’s password unlocks the screen. To prevent unmanaged users from unlocking a screen and accessing primary and secondary accounts, only allow users with a managed Google Account be primary users by setting the Add restrictions on a managed account's usage as a secondary account on ChromeOS policy.
- You can block managed accounts from becoming secondary accounts, even if multiple user sign-ins are allowed, by setting the Add restrictions on a managed account's usage as a secondary account on ChromeOS policy. You can also use this policy on unmanaged devices.
- Secondary users on a device might be able to access your network, even if they don’t have a managed Google Account. For example, apps and extensions that you do not allow users in your organization to install can be installed in secondary accounts. Those apps and extensions might access your network. To prevent unmanaged access to your network, do not let users sign in to more than one account at a time. For more details, see Sign-in to secondary accounts.
