what is a MFA code?

An **MFA code** is a one‑time passcode used in **Multi‑Factor Authentication** when you log in or perform a sensitive action (like withdrawals, changing security settings, etc.). ### What MFA is **MFA (Multi‑Factor Authentication)** = logging in with **two or more types of proof** that it’s really you, for example: 1. **Something you know** – your password or PIN 2. **Something you have** – your phone, hardware key, authenticator app 3. **Something you are** – fingerprint, face ID, etc. ### What the “MFA code” itself is Usually: - A **6‑digit numeric code** (sometimes more/less) - **Short‑lived** (e.g., valid for 30–60 seconds or a few minutes) - Generated or delivered via: - **Authenticator app** (Google Authenticator, Authy, Microsoft Authenticator, etc.) - **SMS text message** - **Email** - **Hardware token** (little device that shows codes) You type this code in **after** your username/password to complete the login or approve an action. ### Security basics (important for trading/prop firms) - Never share your MFA code with anyone (including “support” on email/DM). - If you get an MFA prompt when **you didn’t try to log in**, that can mean someone has your password—change it and lock things down. - Authenticator‑app codes are **safer than SMS**, because SIM‑swap attacks can hijack text messages.
