Click the system menu on the right side of the top bar.

Click Settings.

Click the Online Accounts panel, then click the online account service you want to use.

This will open a new window where you can sign in to your online account.

In most cases, you will have to grant access to the online service after signing in to get started.

For example, if you are connecting to your Google account, you will have to click the Grant Access button.

Many online accounts let you choose the services you want to use with your online account. If you do not want to use a service, disable it by clicking the ON/OFF switch on the right-hand side of the window.
