+## SonarCloud Webhook IPs
+
+SonarCloud performs webhook calls from the following list of IPs:

+52.59.246.1
+54.93.180.144
+18.194.44.125

## Authentication
Primary authentication on the system is available only through OAuth authentication with GitHub, Bitbucket Cloud and Microsoft VSTS. As a consequence, users don’t have a password on SonarCloud, and are as protected as what they expect (especially with 2FA activated on those systems).
