Time-Based One-Time Passwords (TOTP) add an extra level of security around your vital electronic data. Traditional passwords once provided a reasonable barrier between protected content and data thieves. But massive data breaches and published lists of the most commonly used pass codes have reduced the effectiveness of such simple locks.Time-Based One-Time Passwords: A Primer in C# introduces you to the TOTP algorithm, a great tool for enhancing existing password-only systems. Security experts have long encouraged the use of Two-Factor Authentication (2FA) methods, including TOTP, as a supplement to simple passwords. Fingerprint recognition and other biometric solutions require costly hardware or complicated integrations, but TOTP is a simple, straightforward process that developers can incorporate into authentication systems on any platform.In this book, you will learn how TOTP works, why it is important, and how you can use it.- Discover the industry-accepted standards that provide the foundation for TOTP.- Learn the coding tasks required to incorporate TOTP into your system.- Understand how one-time pass codes will impact the user's sign-in experience.- Review the modern, easy-to-read source code and its straightforward implementation of TOTP.The book includes a downloadable C# / .NET companion project. Not only will the project enhance your understanding of TOTP, it also provides a useful starting point for your own 2FA implementations.From new security requirements in your organization to mere curiosity about how the TOTP system works, Time-Based One-Time Passwords: A Primer in C# will fulfill your technical requirements
