 ## Limitations
 
-### Hosted Authentication
-- Cannot create fully custom login/signup UI
-- Base44 provides hosted authentication pages
-- Custom branding available in app settings
+### Authentication UI Options
+- **Recommended:** Build custom login/signup UI using `loginViaEmailPassword()` and `loginWithProvider()` for full control over user experience and branding
+- **Alternative:** `redirectToLogin()` uses Base44's hosted authentication pages with limited customization
 
-### Redirect Behavior
+### Hosted Login (via redirectToLogin)
 - `redirectToLogin()` shows both login and signup options on the same page
 - No separate `redirectToSignup()` method
 - Users can switch between login/signup on the hosted page
+- ⚠️ **Note:** Prefer building custom login UI for better user experience
 
 ### Password Requirements
 - Minimum length and complexity requirements enforced
