TOTP Algorithm Explained

Time-based one-time password algorithm (TOTP) is the focus of this post. But, before we delve deeper into the TOTP meaning, we’d like to mention the organization that is instrumental in the one-time password algorithms’ existence — OATH, or Open AuTHentication. OATH is a collaboration of all sorts of specialists, who made their mission to create a truly secure and universal network for all to use. We at Protectimus are proud to be a part of this collaborative effort.

In this article, we will learn what OATH TOTP is. We will have a closer look at TOTP algorithm implementation and the work of the TOTP mode. Finally, we will provide a full list of Protectimus TOTP tokens designed for time based token authentication to help you choose the one that suits you best.

We’ve already answered the “what does TOTP mean?” question above. But what is TOTP authentication? An uncomplicated answer is — it’s a 2-factor verification method that uses the time as a variable. Let’s expand on this a bit and unravel how TOTP authentication actually operates.
