'Your Amazon account has been locked due to suspicious activity', or a message asking you to confirm an expensive order you never placed, is one of the most-sent phishing lures in the world. Amazon does not lock accounts by text message with a link to fix it. The link leads to a lookalike page that harvests your Amazon password — and since people reuse passwords, often much more.
Nearly everyone has an Amazon account, deliveries make 'order problem' messages plausible daily, and a locked-account threat demands action before thought. The counter is a habit, not vigilance: messages are notifications, never doors — always enter through the app yourself.
There's an order in the message I don't recognise. Could it be real? Check inside the official Amazon app or amazon.com (typed yourself): Your Orders. If it's not there, it doesn't exist — the message invented it. If a real unknown order or charge does appear, that's account compromise: change the password, enable 2-step verification, and contact Amazon through the app.
I entered my password on the fake page. How bad is it? Assume that password is public now. Change it at the real Amazon immediately, turn on 2-step verification, and change the same password anywhere else it was used — email first. Then run the full checklist on the phishing page linked below.
