Vonage 2FA


Vonage Two-Factor Authentication Plugin for WordPress

This plugin enables your WordPress site to use Two-Factor Authentication
using Vonage’s Verify API service.


  • WordPress Version 5.9 and up (i.e. the current supported version of WordPress).
  • An account with Vonage (with credit). You can sign up here.

Setting up:

  1. Install this plugin in your WordPress plugins directory.
  2. Active the plugin under your administrator account.
  3. Your 2FA admin menu should now be accessible from the WordPress menu

  4. Populate your API Key and Secret in order to connect to Vonage’s Verify API that
    this plugin uses. You can get these credentials from your Vonage Dashboard.

  5. Each user of your WordPress site can now enable 2 Factor Authentication from their
    user settings. A new section is available in the Profile screen.

Please note that this phone number must contain the full international dialling code
complete with + symbol.

  1. For users with 2FA enabled, the first login attempt will ask for the PIN sent out
    to the phone number entered.

  2. Once the user has entered a valid PIN, login will finish.

Under the hood, WordPress stores a unique request_id from Vonage in the user’s
session with the key vonage_2fa_request_id. On each login, WordPress
will use the Verify API to make sure this key is still valid. When it expires, the 2FA
workflow will be repeated.
