OAuth is an open standard for access delegation commonly used to grant third-party applications limited access to user accounts without sharing passwords. In the sphere of digital assets, OAuth enhances security by allowing users to authorize apps to interact with their wallets or trading accounts without revealing sensitive information.When a user wants to connect a wallet to a dApp (decentralized application), OAuth facilitates the process by allowing the user to log in using credentials from trusted services. This way, users can securely grant permissions for transactions or data access.By implementing OAuth, developers can bolster the security of their applications. They can define permissions, such as read-only access to balance data or transaction capabilities, ensuring that apps can only perform tasks that users explicitly allow.This system mitigates risks of password misuse and offers a safer user experience through token-based authentication, which can be revoked without changing the main account credentials. Overall, OAuth plays a vital role in enhancing trust and security in interactions involving digital assets.
