Should AI Agents Ever Hold Permanent Payment Credentials? Ephemeral Per-Purchase Credentials Make More Sense
AnySprinkles1242 · reddit · 2026-10-06
A Reddit poster examines how payment access should work for AI agents. Giving an agent a normal card number with a spending limit still leaves a live credential after the task ends — more access than needed if the agent or workflow goes wrong.
The cleaner design proposed: issue a payment credential for a specific purchase with a set amount, expiring after the transaction. The agent gets just enough authority to finish the task, with nothing left to exploit afterward. The author asks agent builders whether they'd trust persistent credentials with limits or prefer per-purchase credentials.
