An authorization token is a digital key that allows access to a certain service or resource within a network or platform. In cryptocurrency systems, these tokens are often used to confirm the identity of users and grant them permission to perform specific actions, like making transactions or accessing accounts.When a user wants to interact with a blockchain, they usually need to authenticate themselves using their wallet credentials. Once authenticated, the system generates an authorization token, which holds information about the user and their permissions. This token is then passed along with requests, ensuring that only authorized users can take actions, such as transferring funds or accessing sensitive data.Tokens enhance security by reducing the need to repeatedly input sensitive information. They can have a limited lifespan or lifetime based on the session, minimizing risks of unauthorized access. Overall, authorization tokens play a vital role in protecting user accounts and facilitating secure transactions in cryptocurrency ecosystems.
