Persistent identity Beta

By default, each session gets a new device. To come back as the same visitor, for example to stay logged in to an account, pass the same identity label each time:

{ "os": "windows", "proxy": "premium", "country": "us", "identity": "account-1" }

• Same device: the first session with a label saves its device. Later sessions with that label report the same screen, GPU, fonts and other device values.
• Same exit IP: with a premium or datacenter proxy, the label also keeps the same exit IP.
• Fresh state: cookies and storage start empty in each session. Save and restore them in your code if you need them.
