How is a session defined in Mixpanel?

Hi Natan D., Please stand by as I search the Mixpanel knowledge base for an AI-powered answer. I normally take about 15 seconds or so.

In Mixpanel, a session can be defined in three different ways: 1. Timeout-Based Sessions (Default): A session starts when a user performs any event and ends when the user is inactive for a set period of time. By default, this timeout is 30 minutes.2. Event-Based Sessions: The session starts and ends based on specific events you choose. For example, you might define "Login" as the start event and "Logout" as the end event.3. Property-Based Sessions: Sessions are defined by a property you choose as the "Session Id". The session persists as long as the value of this property remains constant.It's important to note that sessions are reset every 24 hours at midnight according to your project timezone, so the maximum session length is 24 hours.Project Admins or Owners can choose between these configurations in the Project Settings. Since Mixpanel computes sessions on the fly, you can change this definition at any time and it will apply historically.Sessions: Compute sessions based on existing event data provides more detailed information on how sessions work in Mixpanel.

Based on the information provided in the knowledge sources, there isn't a direct mention of how closing a browser affects session endings in Mixpanel. However, we can infer some information based on how Mixpanel defines sessions: 1. For Timeout-Based Sessions (the default method): The session ends when there's a period of inactivity, typically 30 minutes by default. Closing the browser would likely result in this period of inactivity, so it would effectively end the session after the timeout period.2. For Event-Based Sessions: If you've defined specific start and end events, closing the browser wouldn't necessarily end the session unless you've specifically set an event that triggers on browser close as the end event.3. For Property-Based Sessions: Closing the browser wouldn't directly affect the session unless it changes the value of the property you've set as the Session ID.It's important to note that Mixpanel resets all sessions every 24 hours at midnight (according to your project timezone), regardless of browser state.Sessions: Compute sessions based on existing event data provides more details on how Mixpanel handles sessions, but it doesn't specifically address browser closure.To get a definitive answer on how browser closure affects sessions in your specific Mixpanel setup, you might need to consult Mixpanel's support or conduct tests in your own environment, as the exact behavior could depend on your configuration and implementation details.
