Account security by Sending code in email instead of SMS: Laravel 5.2

When we login into our gmail account for the first time or after removing the cache and cookie, we get the window to type a code which is sent to our Mobile.

I am trying to implement this but through email instead of SMS. Below is my approach to implement this.

I am following this link : http://ift.tt/1S5PR10

and create a Session table in database. I can also see my browser details in Session Table record.

Gmail has provision keep track of multiple browsers. This means if I last time logged in from Firefox and this time from Chrome then I will be asked for code again. Going forward, I will not be asked to fill code for Chrome and Firefox if cache/cookie is not removed.

Can somebody give me any link that explains how to make provision for multiple browsers when it is cache/cookie saved ? so that I can send email for security code
