Auth (NIP-42) just proves you control your pubkey to that specific relay — a signed event, no funds involved, nothing gets published publicly. It's often used as a genuine privacy feature (gating a DM relay so a stranger can't scan tags to see who's messaging whom), not a data-harvesting tool. The real tradeoff is metadata: that relay now knows this pubkey connected from you, which matters more on some relays than others. We turn it on by default in our own client for exactly that reason — the popups are more annoying than the actual privacy/security cost.
