Open Authorization (OAuth) is a protocol that enables secure delegation of access rights. It allows users to grant third-party applications access to their information without sharing their passwords. In the context of cryptocurrency, OAuth is often used to connect wallets or platforms with decentralized applications (dApps).With OAuth, a user can authorize a dApp to access certain features of their wallet, like viewing balances or making transactions, while keeping their private keys secure. This process typically involves redirecting the user to a trusted authorization server, where they can log in and approve the access request. Once authorized, the dApp receives a token that allows it to interact with the user’s wallet on their behalf.This enhances security by minimizing the exposure of sensitive information. Users maintain control, as they can easily revoke access at any time without needing to change their passwords. Overall, OAuth streamlines user experiences while preserving essential security measures in blockchain environments.
