(C#) TOTP Algorithm: Time-Based One-Time Password Algorithm. Demonstrates how to generate an time-based one-time password (TOTP) as specified in RFC 6238. This is the algorithm used by Google Authenticator. Note: This example requires Chilkat v9.5.0.77 or greater. Time-based One-time Password (TOTP) is a computer algorithm that generates a one-time password (OTP) which uses the current time as a source of uniqueness.

Excellent utility - well thought through and works every time. It is now part of my permanent tool set in the chrome browser. Especially thankful for the backup sync to google drive, and local download - makes this tool useful even after a full reset has to happen.

Time-based One-time Password (TOTP) is a computer algorithm that generates a one-time password (OTP) which uses the current time as a source of uniqueness. An extension of the HMAC-based One-time Password algorithm (HOTP), it has been adopted as Internet Engineering Task Force (IETF) standard RFC 6238..
