I am using node js code for alexa app skill.when multiple users are invoking skill. Data is overriding.each launch request getting values of old request from other user.
Only one user can use a specific device at any one time. The session data is specific to a user interaction on an indivudual device. If you have multiple Alexa devices all registered to the same Amazon account then all of them can use the skill simultaneously and each one will have a separate session. Forget the concept of multiple "logins", it's not an issue as long as you store stateful data in the session attributes.
