Registrar Lock is a safety feature that prevents unauthorized domain transfers. By default, this feature is enabled for all your domains.
If you are transferring your domains to NityGity, you may find instructions on how to release Registrar Lock with your current registrar in one of these articles.
If you wish to transfer your domain from NityGity to another registrar, please see this article for instructions on how to release the Registrar Lock on your domain. This must be done before placing a transfer request with a new registrar.
