Remember me functionality can be implemented in login page to save the user details. This can be implemented with the help of cookies. Cookies will stored in browser.
Here's what you need to do:

if (chkRememberPass.Checked == true)
{
Response.Cookies["UserName"].Value = txtUName.Text;
Response.Cookies["PWD"].Value = txtPWD.Text;
Response.Cookies["UserName"].Expires = DateTime.Now.AddMonths(2);
Response.Cookies["PWD"].Expires = DateTime.Now.AddMonths(2);
}
else
{
Response.Cookies["UserName"].Expires = DateTime.Now.AddMonths(-1);
Response.Cookies["PWD"].Expires = DateTime.Now.AddMonths(-1);
}

Paste the following code snippet in page load

if (!IsPostBack)
{
if (Request.Cookies["UserName"] != null)
txtUName.Text= Request.Cookies["UName"].Value;
if (Request.Cookies["PWD"] != null)
txtPWD.Text.Attributes.Add("value", Request.Cookies["PWD"].Value);
if (Request.Cookies["UserName"] != null && Request.Cookies["PWD"] != null)
chkRememberPassword.Checked = true;
}

Normally whenever the user closes the site, his authentication cookie (session id) expires as per the set rules. So when user comes after some time and opens the page he has to login again. Thus to implement remember me, you need to ensure that authentication cookie does not expire unless user clicks on logout button. Set the expires property of auth cookie to some future date.

For ASP.NET :

When using Forms Authentication, pass

true

as a second boolean argument to RedirectFromLoginPage or use cookies

For MVC :

iam using this code in the company's web site check it

in login page in pageload event do the following

If Request.Browser.Cookies Then
                If Request.Cookies("UserName") IsNot Nothing Then
                    txtEmailID.Text = Request.Cookies("UserName").Value.ToString()
                End If
                If Request.Cookies("PassWord") IsNot Nothing Then
                    txtPassword.Text = Request.Cookies("PassWord").Value.ToString()
                    flag = LoginDirectly(txtEmailID.Text, txtPassword.Text) 'function to check login
                    If flag Then
                        Response.Redirect("Default.aspx")
                    Else
                        lblLoginMsg.Text ="Invalid EmailID or password"
                        txtPassword.Text = ""
                    End If
                End If
            End If

and now in button login do the follwoing

     Response.Cookies("UserName").Expires = DateTime.Now.AddDays(30)
            Response.Cookies("UserName").Value = txtEmailID.Text
        End If
        If chkRemMe.Checked Then
            Response.Cookies("PassWord").Expires = DateTime.Now.AddDays(30)
            Response.Cookies("PassWord").Value = txtPassword.Text
        End If

and in logout button do the following

If Request.Cookies("PassWordC") IsNot Nothing Then
            Response.Cookies("PassWordC").Expires = DateTime.Now.AddDays(-30)
        End If
this will delete only the password cookie and will keep the user name or emialID

When using Forms Authentication, pass
true
as a second boolean argument to RedirectFromLoginPage or use cookies

Also, Do not forget to increase the TimeOut value, because it defaults to 30 (minutes). And make sure you add a machine Key to your web.config
