What is OAuth Edge Cases?
The production scenarios that OAuth tutorials don't cover: social login redirect failures when the callback URL is wrong, token revocation when a user disconnects their account, PKCE flow for mobile apps that don't have a client secret, and session invalidation when a user changes their password on the provider side.

Why it matters
OAuth works perfectly in tutorials. In production, users click the wrong Google account, your callback URL changes during deployment, mobile apps need PKCE instead of client secrets, and providers silently revoke tokens. These aren't bugs — they're the OAuth specification working as designed. But AI-generated auth doesn't handle them.
Where AI gets this wrong
How AI tools get this wrong, and why it matters for your app.
AI implements the happy path for OAuth. User clicks login, gets redirected, comes back authenticated. It doesn't handle the user who has three Google accounts and picks the wrong one, or the mobile app that can't store a client secret, or the provider that silently revokes tokens.
