# Session Persistence in Lambda Chat

## post by Anchained on Sep 10, 2025

I was using Lambda Chat while in incognito mode and when I opened a new incognito tab or window my previous chats persisted even without signing in. How does this work under the hood? Can someone link a resource or give a brief explanation so that I can dig further on how it works and can be implemented.
