How to Secure Your Domain — A Practical Guide

Losing your domain is one of the most devastating things that can happen to an online business or project. It happens through compromised registrar accounts, social engineering, or simply neglected security settings. Here's how to make sure it doesn't happen to you.

1. Enable Two-Factor Authentication on Your Registrar Account

This is the single most impactful security measure. If an attacker gets your registrar password (through phishing, data breaches, or password reuse), 2FA stops them from making changes to your domain. Every major registrar supports 2FA — enable it now if you haven't.

• ▸Use an authenticator app (Google Authenticator, Authy) rather than SMS 2FA — SMS can be SIM-swapped
• ▸Store your backup codes in a password manager or secure offline location
• ▸Make sure 2FA is also enabled on the email account associated with your registrar

2. Enable Domain Lock (Registrar Lock)

Most registrars offer a "domain lock" or "transfer lock" feature that prevents your domain from being transferred to another registrar without additional verification. Enable it. There's no downside — you can still update DNS records and other settings; it only prevents unauthorised transfers.

3. Use a Strong, Unique Password

Use a password manager to generate a unique, strong password for your registrar account. Never reuse passwords across services. If one site is breached and you reuse passwords, every account with that password is at risk.

4. Keep Your WHOIS Contact Information Accurate

Your WHOIS information (name, email, address) is used to verify domain ownership in disputes and transfers. Inaccurate or outdated contact details can cause you to miss critical notices, or give attackers a way to claim you're not the legitimate owner.

5. Enable DNSSEC

DNSSEC (DNS Security Extensions) adds cryptographic signatures to DNS records, preventing DNS spoofing attacks where an attacker redirects your domain's traffic to a malicious server. If your registrar and DNS provider both support it, enable it.

Cloudflare makes DNSSEC easy — it's a single toggle in the DNS section of your dashboard. Enable it, then copy the DS record to your registrar.

6. Set Up Domain Expiry Alerts

Domains expire. If you miss the renewal, someone else can register your domain the moment it becomes available. Set up alerts well in advance:

• ▸Enable auto-renew at your registrar (most support this)
• ▸Set calendar reminders 60 and 30 days before expiry
• ▸Keep your payment method up to date at your registrar
• ▸Don't use a card that expires before your domain does

7. Monitor Your Domain's DNS Changes

Set up monitoring to alert you if DNS records change unexpectedly. Tools like DNSstatus.app or Uptime Robot can monitor DNS and send alerts. If someone changes your A record or MX record without your knowledge, you'll know immediately.
