About Session or Cookies

Question

I am using Session to store Id and Other fields (such as: UserId, Phone, Email) after Login and Signup.

But the session gets expired after some time. So anyway I can keep the session alive. I tried some online solutions but didn't work

 

Also, tried  Cookie, but do I need to create Cookie for every field (such as UserId, Phone, Email) and then retrieve it on all pages?

 

I am using MVC OrmLite.

 

Thank you in advance.
