Will it affect users registering via social login or third-party plugins?

Depends on How the Plugin Creates the User

Social login plugins typically bypass the standard WooCommerce registration form and create users automatically upon login.

Compatibility Summary

• Compatible if the plugin uses WordPress hooks like:
  • user_register
  • woocommerce_created_customer
• May Skip Approval if:
  • The plugin assigns roles immediately and doesn’t trigger approval logic.
  • The plugin logs in users before the approval process is applied.

Best Practices

• Use the role-based settings to exclude roles that shouldn’t need approval (e.g., “Social User”).
• Test a registration using social login to verify whether the user is:
  • Listed in Pending Users
  • Restricted from logging in or checking out
