Sign-in integrations allow customers to connect with our supported platforms — Facebook®, Google®, or X™ (formerly Twitter™) — to quickly sign up or log in to WHMCS.
WHMCS's default captcha option displays an image with six characters on a striped background. This option does not require additional configuration or an additional account with a captcha service.
You can choose from several supported mail providers for your WHMCS installation, including Google™, Mailgun, Microsoft®, PHP Mail, SendGrid, SMTP, or SparkPost.
Set up email importing using POP3 or IMAP with a Google® email account. WHMCS will import the email replies from this account into the correct support tickets.
Set up email importing with OAuth2 using Google®. Email importing with Google using this method includes additional security benefits with OAuth2 authentication.
You can configure Google as your mail provider using SMTP. This requires creating an app in the Google Cloud console and configuring SMTP as your mail provider.
