Whitelisting is the practice of identifying entities that are provided a particular privilege, service, mobility, access or recognition. Entities on the list will be accepted, approved and/or recognized. Whitelisting is the reverse of blacklisting, the practice of identifying entities that are denied, unrecognised, or ostracised.
CoinDeal adheres to the latest security standards and helps prevent unauthorized entries to your account through authorization of each IP that attempts your account log in. Each time you enter your account from different location or device that has an IP not yet whitelisted (meaning associated with your account), you will be asked to confirm that it is you who wants to log in. Once you confirm the new IP, this IP will be associated with your account going forward and you will be able to log in from this IP in the future.
