Registrar lock (or domain lock) is a security mechanism that prevents your domain from being transferred to another registrar without your explicit authorization. When enabled, any transfer attempt is automatically rejected. It's your first line of defense against domain hijacking. Registry lock (different from registrar lock) goes further by requiring manual verification by the registry for any change. For critical domains, both protections are essential.
When to Check Your Lock
- You receive transfer request emails you didn't initiate
- Whois shows a status different from "clientTransferProhibited"
- You have doubts about your registrar account security
- You manage high-value or well-known brand domains
Protection Types
- Registrar Lock (client): Basic protection, activatable from your panel. Blocks unauthorized transfers at registrar level.
- Registry Lock (server): Premium protection at registry level. Requires manual verification (often by phone) for any change.
- DNSSEC: Not a lock but a cryptographic signature that authenticates your records and detects modifications.
Verification and Activation
- Check current status: whois example.com and look for "Domain Status: clientTransferProhibited".
- Log into your registrar panel and locate the "Domain Lock" or "Transfer Lock" option.
- For registry lock, contact your registrar - it's usually an optional paid service.
- Also enable 2FA on your registrar account for complete protection.
