🔐 Authentication is not just a login screen.
In mobile apps, auth often becomes one of the messiest parts of the product because it touches almost everything:
• onboarding
• email verification
• password reset
• social login
• session refresh
• token expiration
• biometrics
• permissions
• deep links
• account deletion
The mistake is treating authentication like a one-time setup task.
For React Native apps, I prefer to think about the full session lifecycle from the start: what happens when the token expires, the app returns from background, the user changes devices, or a request fails halfway through.
A clean auth flow makes the whole product feel more reliable.
Good authentication is invisible when it works — and graceful when it doesn’t. 🔑
