The two-factor authentication is a more widely spread method of putting account safety into the hands of the holders. In other words, each individual gets to decide if they want to activate it, and thus receive a one-time-use code to their specified mobile device upon each login.
Neteller still employs its own security and protection measures – encryption certificates and other methods. These meet the standards of the industry, and other leading businesses of the same kind, such as Skrill and PayPal.
Secure ID is the latest measure implemented for this purpose – it basically represents a 6-digit code provided by Neteller specifically for your account. It should be kept private, away from anyone apart the account holder, as it is used as an additional means of identity verification for all procedures – login, money transfer, exchange.
