The HIDDEN MATH Behind Your 6-Digit Code #howitworks #facts #mindblown

Every time you log in, your phone and the bank's server are solving a complex math problem using a secret method called TOTP (Time-based One-Time Password). 🤯 This video exposes the HIDDEN MATH that generates your 6-digit security code and reveals that your code isn't random at all—it's based on a secret key and the exact time. We break down the incredible engineering that makes this number predictable yet unguessable, protecting billions of dollars of transactions every single second. Watch to learn why your security code expires so quickly and how a simple clock is the key to modern banking!
