How to keep a user logged in

Is the only way to use session cookie if I wanna keep a user logged in even if he has restarted the comput开发者_运维问答er?

I would appreciate all kinds of solutions for different scenarios.

I am using Node.js/Express.

I would say yes : keeping his IP will not work every time.

Depending on your context (intranet application most often), you may also have a look at SSO solutions like kerberos
