The “Devices & sessions” section of your Security
setting page allows you to see what device and connection session currently
exist for your account.
You can take action like remove the connection (Revoke) or initiate a Wipe device request to the connected device.
At the bottom you will find a button to create a new device-specific password. You can choose a name to identify the token later. The generated password is used for configuring the new client. Ideally, generate individual password (token) for every device you connect to your account, so you can disconnect those individually if necessary.
