How to build a one-time passcode protected conference line

We’ve seen how to build a conference line and then protect it with a static passcode. However, passcodes can be guessed or leaked, especially if they are reused over time. An alternative is to make a list of numbers that are permitted to join the call. But, since spoofing phone numbers is relatively easy, this still may not protect you.

A one-time passcode (OTP) sent to a caller’s phone or email, can verify they are who they say they are and increase the security of your conference line once more.

In this post we will take the Rails application we previously developed and add a conference line secured in two ways. We will:

  1. Ensure that the caller is a known participant by checking their caller ID against a list of permitted phone numbers
  2. Send them an OTP using Twilio Verify which they then have to enter correctly to ensure they aren’t spoofing the number

How To Set Up Two-Factor Authentication in cPanel

What is 2FA
Two-Factor Authentication (or 2FA as it often referred to) is an extra layer of security that is used to provide users an additional level of protection when securing access to an account.
Employing a 2FA mechanism is a vast improvement in security over the Singe-Factor Authentication method of simply employing a username and password. Using this method, accounts that have 2FA enabled, require the user to enter a one-time passcode that is generated by an external application. The 2FA passcode (usually a six-digit number) is required to be input into the passcode field before access is granted. The 2FA input is usually required directly after the username and password are entered by the client.

How to Install and Configure Chrony

It is essential to keep the correct time on a server. This is especially true when it comes to processing financial transactions or other vital functions which need to be handled in a specific order. Using the Network Time Protocol (or NTP), computers can synchronize their internal clock times with the internet standard reference clocks. In essence, NTP is a hierarchy of servers. The higher the Stratum number of a server, the more accurate the timing is and the lower the Stratum number of a server is, the lower the accuracy and time stability. Stratus are defined by the distance from the initial reference clock.
