Explains the OAuth authorization code flow with PKCE (Proof Key for Code Exchange) for mobile apps that connect directly to an auth service without a backend intermediary. Covers how a code verifier and challenge are generated, why the challenge is sent on the initial redirect, how the auth service stores and validates it, and why this prevents malicious actors from intercepting and reusing the one-time authorization code to obtain tokens.
