InstaTunnel supports two levels of authentication: creating an account for enhanced features, and securing your tunnels with password protection or basic auth.
InstaTunnel works immediately without any signup. Perfect for quick testing and development.
Simple password protection - visitors need to enter the password before accessing your tunnel.
Standard HTTP Basic Authentication - more secure than simple password protection.
🔒 Security: Never hardcode passwords in scripts or commit them to version control. Always use environment variables.
