A one-time password (OTP) or two-factor code exists to prove a login attempt is really you. The single rule that prevents most account takeovers: never share that code with anyone, no matter who they claim to be or how urgent they make it sound.
OTPs and two-factor authentication get mentioned throughout this site’s guides in passing. This page is the fuller explanation of what they actually do and why the one rule around them matters as much as it does.
What an OTP is actually for
A one-time password is a short code sent to your phone or email specifically to confirm that whoever is logging in also has access to that device or inbox — proof that the login attempt is really you, not just someone who guessed or stole your password. It has no other purpose.
Why sharing it defeats the entire point
The moment you share an OTP with someone else, you’ve handed over the exact proof-of-identity it exists to protect. This is why “read me the code to verify your account” is one of the most consistently effective scam scripts across every platform category, not just gaming apps — it turns the victim into the one who unlocks their own account.
What two-factor authentication adds beyond a password
Two-factor authentication (2FA) requires a second, separate proof of identity beyond your password — usually a code, sometimes a biometric check or a separate authenticator app. If a platform offers real 2FA (not just an OTP at login, but an actual second factor you control), enabling it is one of the highest-value single actions you can take for that account.
The practical rules
- Never share an OTP or 2FA code with anyone, including someone claiming to be support — see our guide to recognizing fake support for why that claim is almost always the scam itself.
- Enable 2FA wherever a platform genuinely offers it, not just an OTP at login.
- Be suspicious of any request for a code you didn’t personally trigger by trying to log in yourself.
This is a small habit with an outsized effect — most account-takeover scams in this space depend entirely on getting a real user to bypass their own protection.
