# What is TOTP?

TOTP stands for **Time-Based One-Time Password.**
It is a temporary security code generated by an authenticator app. The code typically changes every 30 seconds, providing an additional layer of security for your account.
For Set Your Vector, if you choose TOTP during MFA (Multi-Factor Authentication) setup, you will:
Scan the QR code using an authenticator app.
The app will generate a 6-digit verification code.
Enter the code on the Set Your Vector website to verify your identity.
Once TOTP is set up, your authenticator app will generate a new code whenever you need to verify your identity.
