## AI overview

The article presents progressive authentication for RAG systems: answer public questions without sign-in, then authenticate within the conversation when a request requires access to sensitive personal data. It argues that static, upfront authentication does not fit conversations that shift between public and private contexts.

## Source excerpt

Designing a production-ready RAG architecture where authentication becomes part of the conversation, not a prerequisite for it. By Aishwarya Murali Padikkal & Priyank Solanki From understanding to retrieval, grounding, and response, authentication enters only when the conversation requires access to sensitive data- illustrating the core idea of progressive authentication. Illustration generated using ChatGPT and refined by the authors. Two questions, one help line Imagine two taxpayers opening the same AI-powered tax assistant. The first asks, "When is the filing deadline this year?" The second asks, "What was my refund last year?" Both questions are valid. Both deserve fast, helpful answers. Yet they represent fundamentally different types of requests. Figure 1. The same assistant, two different journeys. Requests are routed according to the type of information being accessed. Illustration generated by AI (ChatGPT) and refined by the authors. The answer to the first lives in a public handbook. Anyone should be able to access it instantly- no sign-in, no friction. The answer to the second is within an individual's private tax records. Before revealing a single detail, the assistant must be certain it is interacting with the right person. Making public information instantly accessible while ensuring private information is revealed only to the right person, all within the same conversation, is the challenge we set out to solve. It is also where conventional RAG systems quietly fall apart. Traditional RAG architectures assume a much simpler interaction model: a user asks a question, the system retrieves relevant documents, and the model generates an answer. Authentication, if it exists at all, is treated as a one-time checkpoint at the start of the interaction. Real conversations are far less predictable. Users naturally shift contexts, starting with a public question, moving to a personal one, and then asking follow-up questions that rely on both. The conversation evo
