Auth you won't regret
Authentication is easy to get wrong in ways you won't notice until it's too late. Two notes on doing it safely.
1. Don't roll your own
Auth is full of subtle traps you won't spot until there's a breach. Lean on a proven provider or library, and spend your effort on the product only you can build — not on reinventing login.
2. Sessions vs tokens, on purpose
Pick your auth model for reasons you can explain — revocation, scale, where state lives — not because a tutorial used it. The wrong default here is painful and slow to undo later.
