How to prevent same login details with multiple browser in codeigniter

Question

How do i stop multiple user login with same email and password once the user already logged into the website.

For example:

if a  user already login from chrome and user trying to login from firefox
then system should automatically destroy first session which is created 
from chrome.

I think you need to store user info which is logged in and check with them if login from another place/browser. — Jaydeep Mor, Mar 13 '18 at 06:19

You can use the method mentioned in above link just instead of merging the session, destroy the first one and create new one. — SRK, Mar 13 '18 at 06:25

The solution is to store your sessions in a database. Then when a user re-attempts to login you can easily delete them from the database. You would probably require a table that stores a session-userID link but that is kinda the solution I use.

You can add a field like "is_loggedin" in your user table And update this field value to 1 when any user login. And update it to 0 when any user logout.

At the time of login you can check this field value if it is 1 than user is logged in at other place and you should return your warning message.
