(Java) 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.

Oct 09, 2020 · Time-Based OTP Authentication algorithm (TOTP) is a multi-factor authentication. In this post we will implement this algorithm using pure PLSQL. To understand the algorithm in depth and to get the Java based implementation please visit the IETF website. This temporary code is generated by a secure algorithm. Enabling 2FA can prevent you from upto 80% of the cyber attacks. 2FA is supported by majority of the online services including: Google, Facebook, Github, Epic Games, Evernote, etc. The extension only acts as a supplement to the TOTP Authenticator mobile app.

TOTP implementation, based on the RFC but spiced up with a couple extra methods. Unit tests, to make sure that our implementation conforms with the RFC AppService, that uses the accessKey to retrieve an application from the data store and use the secretKey to generate the TOTP. If it's a match, send a 200 OK back to the caller.
