[FIXED] How to limit login only for 5 devices in spring boot?

Issue

I am working on an Api for login and logout (Spring boot).

There is requirement that an user is allowed to login only in 5 devices.

How i can implement this using spring boot?

Solution

In the case of device if you allow only 5 registered device to be able login than you have to maintain it in database.

But if you want any at most 5 device able to login at same time than try this - https://docs.spring.io/spring-session/docs/current-SNAPSHOT/reference/html/spring-security.html#spring-security-concurrent-sessions

use maximumSessions(5)

http
    // other config goes here...
    .sessionManagement()
                    .maximumSessions(5)

This will allow only 5 session at a time for same user
