Session Keys are meant to be used as secondary signers in your program, especially for frequent interactions like liking a post or moving a piece in a game of chess where constant popups can get in the way of smooth user experience. **They are not burner wallets**. Session Keys work in tandem with our on chain program to validate the token and it's scope. ## **Session Keys have two components** 1. An **Ephemeral Keypair**, intended to be used as a **secondary signer** in the target program. 2. A **Session Token**, a PDA containing information about **expiry and scope** of the keypair. ## **How do they work?** Session keys lifecycle * Ephemeral Keys are stored on the client side, to invoke transactions. * The transactions invoked by these ephemeral keys are validated in the target program for their validity, expiry and scope. * Every transaction needs to present both the ephemeral signer and the session token * This is the general idea behind *account abstraction*, where instead of just an externally owned key there is also smart contract that enhances security.
