Basically, you want to change your password to something new, and then log everyone out of your account. That way, your streaming stalker can’t access your account again (unless you tell them the new password, which you shouldn’t do). 5. Browse the devices and look for one that looks unfamiliar. Click the Remove button for unrecognized devices. Now, everyone who was previously logged into your Netflix account will be logged out, and can’t access your account without the new password. 4. Enter your password, and then type in a new password in the text box that opens up. 4. Follow the instructions and set a new password. 6. Deregister any unfamiliar devices. 4. Return to the settings page, and select the Devices option on the left-hand side of the screen.
