Back-to-Basics: What Is TOTP

TOTP is an acronym of Time-based One-Time Password. It is a temporary passcode generated using an algorithm for authenticating users. Time-based one-time passwords are normally used for two-factor authentication (2FA) and have been widely adopted by cloud-based providers. That said, most internet users have used Time-based one-time passwords (TOTP) at home or at work for common consumer-centric online services.

In this article, we will discuss Time-based one-time passwords (TOTP), the difference between TOTP and OTP, and the benefits of TOTP.

What is TOTP?

If you have been using a dedicated authenticator application such as Microsoft or Google, you might have noticed that these apps generate a unique 6-digit code that resets over a specific period of time. This code is known as the Time-based One-Time Password (TOTP), which allows you to authenticate to the various systems by inputting the code when prompted.

Time-based one-time passwords require that the system which generates the code and the system which receives the code uses a shared key and have a synchronized clock. After this, both the system calculates the matched pair of codes which are valid for a specific duration. At the user end, they are asked to type the code into the system that they are trying to log into. The system then compares the code with the one that generated it. If the codes match, the user is allowed to log in.

You might also have come across the use of one-time passwords. Many people confuse and think that both TOTP and OTP are the same. However, there is a difference between the two.

Difference Between TOTP and OTP

OTP or one-time password is generated randomly and sent to your email or registered phone number for gaining access to your account or to authenticate a transaction. Having said that, while TOTP are valid for only 30 – 60 seconds, OTP is generally valid for about 5 – 10 minutes. Moreover, while TOTP is generated through a mobile application, OTP is sent to you through email or text messaging.

Benefits of TOTP

1. Scalability

First and foremost, TOTP is very easy to scale. Businesses can implement TOTP at scale across their IT resources, with the right provider. These resources can include several applications, file servers and networks.

2. Easy to Use

TOTP is extremely easy to use across a few different channels and applications. Moreover, it provides users with greater security and enhanced authentication mechanisms.

Final Thoughts

Along with a regular password, TOTP is used for two-factor authentication and to offer an added layer of security to the user.
