We've all heard the database horror stories. An intern accidentally exposes a customer's personally identifying information (PII) through a search API. An agentic application deletes an entire database in production. What starts as a simple oversight can quickly become a security incident, a compliance violation, or worse—a headline.
Much of this can be prevented by having the right security setup. This means knowing who is accessing the database (authentication), and only giving appropriate, predefined access to that user (authorization).
As vector databases move from prototype to production, often containing embeddings of sensitive customer data, proprietary documents, or regulated information, getting security right isn't optional. Whether you're a solo developer building your first AI application or a growing team preparing for production, understanding Weaviate's authentication and authorization options is essential.
In this guide, we'll explore what authentication and authorization mean in practice, what options Weaviate provides, and how to implement them for your use case.
