OTP Safety: How to Use Verification Codes Without Getting Scammed
Rule one: an OTP is a key, not a message
A one-time password (OTP) proves that the person logging in controls the email address or phone number on the account. Whoever has the code, has the key — the system cannot tell the difference between you typing it and a scammer typing it. That is why every safety rule below follows from one sentence: never share an OTP with any person, for any reason, ever. No bank, no company, no "support agent", no courier and no government officer will ever legitimately ask you to read a code out to them. If someone asks, the conversation itself is the scam — end it.
The three classic tricks
- The fake official. A call or WhatsApp message from "the bank", "the courier" or "the platform" says there is a problem with your account or parcel and asks you to share the code that "just arrived". In reality the scammer is logging into your account at that moment and needs your code to finish.
- The fake page. A link leads to a pixel-perfect copy of a login page. You enter your password and code, and the scammer uses both in real time on the genuine site. Always check the address bar, and reach important sites by typing their address yourself — never from a link in a message.
- The friendly buyer or seller. In marketplace scams, the other side sends a "payment confirmation" link or asks for a code to "release" money. Real payments never need you to hand over a login code.
A code arrived that you did not request
Do nothing with the code — an unused OTP expires on its own within minutes. But treat it as a warning: someone may know your email address or password and is trying to get in. Change that account's password from the official app or website, check its recent login activity, and turn on two-factor authentication if it is not already on. If codes keep arriving, the attempts usually stop once the password is changed.
Safe habits when receiving OTPs by email
- Request a code only when you are actively logging in or signing up, then use it promptly — codes expire quickly by design.
- Enter the code only on the same site or app that you asked to send it. A code for one service is never typed into another.
- Use a strong, unique password for your main email account; it is the master key that resets everything else.
- For throwaway signups, use a temporary inbox so codes for unimportant accounts never touch your real email at all.
- Never receive OTPs for important accounts — banking, wallets, government — in a temporary inbox. Those codes belong to an address only you control, permanently.
