Unlocking your domain disables the security mechanism that prevents a domain name from transferring between registrars.
As soon as you're ready to transfer your domain, there are two steps involved: retrieving your EPP, unlocking your domain & disabling whois privacy.
To unlock your domain at Bluehost, follow these instructions:¶
- Log into your bluehost control panel.
 - Click the Domain Manager tab.
 - Click the Domain name to highlight it. The right side will populate with tabs.
 - Unlock the domain on the LOCK tab.
 - Turn off privacy on the PRIVACY tab.
 - You will receive an email with an Auth code and a link. Follow the instructions in the email.
 - All set, now you'll need to request your EPP if you haven't, & transfer.
