User Authentication and Authorization

User authentication and authorization are critical components of Kaiju Wallet's security architecture. Kaiju Wallet employs advanced techniques to ensure that users can securely access their wallets and perform transactions with minimal friction

Social Login Integration

Kaiju Wallet leverages social logins to provide a seamless and secure user authentication experience. Users can authenticate using a variety of social identity providers, allowing them to choose the method they are most comfortable with. This integration not only enhances usability but also leverages the security measures inherent to established social platforms.

• OAuth 2.0 and 2.1 Compliance : Kaiju Wallet adheres to the best practices outlined in the OAuth 2.0 and OAuth 2.1 specifications for obtaining and managing tokens from identity providers. These practices include secure token exchange protocols, stringent token expiry policies, and robust mechanisms for revoking compromised tokens.
• Token Expiry and Renewal : To minimize the risk associated with token theft, Kaiju Wallet enforces strict token expiry times. Users are required to obtain a new token for each transaction, ensuring that any stolen tokens have a limited lifespan and cannot be reused indefinitely.

Fine-Grained Access Control

To further enhance security, Kaiju Wallet implements distinct access levels for different API functionalities:

• Transaction API Security : The transaction API, being the most security-sensitive component, operates under stricter access controls compared to other wallet APIs. This separation ensures that even if less critical parts of the system are compromised, the transaction API remains secure, and importantly user's funds and assets remain secure.
• Layered Access Controls : By segmenting access levels, Kaiju Wallet ensures that high-risk operations, such as transaction approvals, are protected with additional security layers. This reduces the attack surface and limits the potential impact of any single vulnerability.

Token Security and Developer Guidance

While securing access tokens on the user's end is beyond the direct control of Kaiju Wallet, we provide comprehensive guidance and support to app developers to ensure that tokens are managed securely within their applications:

• Developer Best Practices : Kaiju Wallet offers detailed documentation and support for implementing secure token management practices. This includes following the latest recommendations from the Internet Engineering Task Force (IETF) for OAuth 2.0 for browser-based applications.
• Education and Support : We work closely with app developers to help them understand and implement secure storage and handling of OIDC tokens, ensuring that they follow industry best practices and mitigate common security risks.

By combining these advanced authentication and authorization strategies, Kaiju Wallet provides a robust security framework that protects users' assets and transactions. Our approach leverages the strengths of established social login systems while implementing stringent controls to manage and protect access tokens, thereby enhancing the overall security of the wallet.
