Hi, To restrict login sessions across browser windows in PHP, you can use a unique session token stored in the database and linked to the user ID. When a user logs in, generate a token, store it in both the session and the database. On every page load, verify if the session token matches the one in the database. If it doesn't, force a logout. This method ensures only one active session per user, preventing multiple logins from different tabs or browsers.
