GoUltra Auth adds a WhatsApp one-time code as a second factor at login. After the password is
accepted, the user enters a short code delivered to their WhatsApp, so a leaked password alone
is no longer enough to get into the admin.
It connects to the GoUltra service, which delivers the code through a WhatsApp
Authentication-category message approved by Meta.
Why WhatsApp (an honest comparison)
WhatsApp authentication codes are not delivered through the SMS network, which reduces exposure
to common SMS delivery and interception risks (such as message interception, poor reception,
and certain SIM-swap scenarios). No authentication method is unbreakable, so GoUltra Auth also
includes rate limits, recovery controls and an audit log. It usually costs less than SMS in
most markets and arrives over Wi-Fi without a cellular signal.
What you get in this version
Recovery and lockout protection
You can always get back in without WhatsApp: enter a recovery code, add
define( ‘GOULTRA_AUTH_DISABLE’, true ); to wp-config.php, or run wp goultra-auth disable.
This plugin sends the WhatsApp phone number you provide, and a one-time code, to the GoUltra
service so the code can be delivered over WhatsApp. No message is sent until you connect the
plugin with a GoUltra API key and a user enrolls a number.
