There are two types of cookies: session cookies and persistent cookies. Web browsers normally delete session cookies when the user closes the browser. Unlike other cookies, session cookies do not have an expiration date assigned to them, which is how the browser knows to treat them as session cookies.
If a cookie does not contain an expiration date, it is considered a session cookie. Session cookies are stored in memory and never written to disk. When the browser closes, the cookie is permanently lost from this point on. If the cookie contains an expiration date, it is considered a persistent cookie.
What is the lifetime of a cookie?
By doing this, we find a bimodal distribution like the histogram below: a large percentage of cookies live for less than a day (~40%), few cookies live for between 1 and 30 days, and the relative majority live for longer than a month (~45%).
How long do chrome session cookies last?
If there’s no expire it’s going to be around until the browser is killed. Normally in ASP.Net the session cookies are set with a 20 minute timeout. That’s usually pretty good. Depending on your app, you may want a javascript timer as well.

Actually, technically cookies are more secure than sessions are. Since sessions are based on cookies they can only be as secure as cookies are, and almost always less secure than that. However, unless you have a very good implementation, sessions will be safer for you.
Importantly, the server-side session that corresponds to the cookie value has a completely independent lifetime that is defined on the server. HTTP is a connectionless protocol, so when your browser isn’t in the middle of a transaction, the server side has no idea whether you’re still there or not.
How are cookies dependent on the browser session?
