It is recommended to change the password regularly. This is especially true on Chromebooks since you use your Google account to sign in. Fortunately change password on a Chromebook is pretty easy.
If you’re using a Chromebook, there’s a good chance you’re using Google services on your other devices. For example, you can write a Google Doc to a Chromebook and then read it on your iPad, mobile phone, or any other device. It all happens through your Google account and you can access all the files in Google Drive using just one password.
You also use your Google account to sign into your Chromebook, and changing your password on your Chromebook will also change it for your Google account. The next time you switch to using Google services on another device, you’ll be prompted to sign in with a new password.
How to change your password on a Chromebook
Start by opening a new Chrome browser window.
Select your profile photo in the top right corner, then select your Google account.
Select Login & Security.
