# `LLMProxy.Providers.OpenAICodex.OAuth.Login`
[🔗](https://github.com/elixir-vibe/llm_proxy/blob/v0.3.1/lib/llm_proxy/providers/openai_codex/oauth/login.ex#L1)

Interactive OpenAI Codex OAuth login for standalone LLMProxy releases.

The browser-facing OAuth protocol returns JSON/string-keyed provider data.
This module owns that external boundary and converts successful token responses
into `LLMProxy.Providers.OpenAICodex.OAuth` credentials for storage.
