## TOTP Algorithms

Time-based One-Time Password algorithms are a standard method for generating temporary, short-lived passwords based on the current time and a shared secret key. In financial applications, this is a common second factor used to verify user identity during login or transaction authorization.

The algorithm ensures that the code is valid only for a short window, typically 30 to 60 seconds, making it difficult for an attacker to reuse intercepted codes. While more secure than static passwords, it is vulnerable to real-time phishing attacks where an attacker intercepts the code as the user enters it.

Therefore, it is often used as part of a broader, multi-layered security strategy. It is widely supported by mobile authentication apps and hardware tokens, providing a convenient and familiar user experience.

For many retail users, it remains the primary form of enhanced security for their trading accounts. Its simplicity and ubiquity have made it a standard in the digital finance industry.

However, its limitations necessitate more robust alternatives for high-security environments.
