# Session Keys

Session keys allow Dapps to sign transactions on behalf of a user with specific limitations, such as expiry time, token limit, etc.

Each zKey login assigns users a session key with an expiry time, allowing them to autonomously sign transactions in a Dapp. This enables an immersive gameplay experience without the need to handle every transaction. Users only need to log in again and obtain new session keys when the session key expires or they lose their keys.
