2 Factor Authentication

Earn the trust of your customers by protecting their critical personal data

Passwords alone are not enough to guarantee data security. 50% of consumers let retailers save their personal data, and today’s leading retailers protect this data using two-factor authentication. This provides an added level of security, which in today’s world is an essential requirement for every application.

Two-factor authentication (or 2FA) adds a second layer of protection in addition to your password - typically a code from a device that the user carries on their person. Adding this additional security layer makes it much harder for hackers to break into your accounts, and ensures your customers’ data remains secure.
