WebAuthn Guide for MySQL, PostgreSQL, SQLite & MongoDB

Introduction: The Importance of Passkeys in Modern Authentication

In the digital age, ensuring the security and ease of user authentication is important. With the advent of passkeys, a new standard in login technology has emerged, offering a user-friendly and secure alternative to traditional passwords. This guide aims to demystify the integration of passkeys across various database technologies - MySQL, PostgreSQL, SQLite, and MongoDB - highlighting key considerations and providing a foundation for developers looking to implement this innovative authentication method in their applications.

Understanding Passkeys: A Developer’s Perspective

Passkeys, based on the WebAuthn protocol, represent a significant leap forward in authentication technology. They replace passwords with cryptographic credentials, enhancing security and user experience. However, integrating passkeys into your application requires a solid understanding of database schemas tailored to store essential data, such as user details and credentials. This article outlines recommended database schemas for popular database technologies, ensuring developers have the know-how needed to implement passkeys efficiently.

MySQL & PostgreSQL: Relational Databases for Passkeys

For relational databases like MySQL and PostgreSQL, the schema involves two primary tables: users and credentials. The users table stores basic information, including username and contact details, while the credentials table holds cryptographic data, such as public keys and attestation types. 

SQLite: The Lightweight Solution

SQLite offers a simple, serverless solution for smaller applications or development stages. Similar to MySQL and PostgreSQL, the SQLite schema consists of users and credentials tables but is tailored for environments where simplicity and minimal overhead are critical. Despite its lightweight nature, SQLite adequately supports the storage requirements for passkey-based authentication.

MongoDB: NoSQL Flexibility for Passkey Storage

MongoDB stands out for its flexibility and scalability, using a document-oriented approach to store data in JSON-like documents. This makes it ideal for applications requiring rapid iterations and adaptable data models. For passkeys, MongoDB’s schema validation feature ensures data integrity, with collections for users and credentials designed to accommodate the dynamic nature of document-based storage.

Conclusion: Embracing the Future of Authentication

Integrating passkeys into your application’s authentication process is not just about enhancing security; it’s about improving the overall user experience. Whether you opt for a relational database like MySQL or PostgreSQL, a lightweight solution like SQLite, or a flexible NoSQL option like MongoDB, the key is to understand the specific requirements and best practices for passkey storage. By adopting passkeys, developers can contribute to a safer, more user-friendly digital world. To see the full database schema recommendations, have a look at our detailed blog post.
