You can use any Google Account with your Acer Chromebook. So if you have multiple accounts, sign in with any account you'd like to use. Similarly, friends who want to borrow your Chromebook can sign in with their own Google Accounts. That way, you can be sure that no one else will have access to your email and personal data.
- Turn on your Chromebook and make sure you are connected to the internet.
- Sign in using your Google Account (Gmail address), or click Browse as guest to login as a guest.
