What Digital Wallets and Keys Are

Digital wallets and keys are tools for storing, presenting, and protecting digital value and identity. A wallet is not always a place where money lives; it can also hold credentials, passkeys, tickets, memberships, and permission settings. Keys are the security mechanism that prove you are authorized to use what is in the wallet.

This lesson introduces the core ideas behind modern wallets and keys, explains how they differ from traditional passwords and account logins, and shows why control, recovery, and trust matter. The focus is on foundations: what these systems are, why they exist, and how they support secure access in everyday digital life.
