Question

As the title implies, the automatically login system is wildly used by many websites. But I could not figure it out by myself. Could you please give me some hint.

EDIT: Yes, I mean the remeber me feature like google.

thanks.

Answer 1

“Remember me” type logins on a site are very simple to implement. There’s nothing magical about it. The two major changes are:

1. Toggling “remember me” to on sets a permanent session cookie instead of a temporary one
2. The server-side session is not automatically cleaned up/garbage collected for a fixed period (e.g. “Remember me for 30 days” means the login part of the session stays around for 30days).
