My friend, there are people are out there telling their AI personal assistants to go on Amazon and purchase a surprise present for themselves based on their known preferences. And then they intentionally do not inspect what the AI purchases because it would ruin the surprise.
People have wildly different risk calculators.
Ordering from Amazon is way less risky than a password vault imo. The password vault does not have a return policy, for starters.
Beyond that, access to logins enables buying things on Amazon, sending emails to everyone you know, registering domain names and spinning up servers, stock trading, etc.
