Two-Factor Authentication

In today’s online environment, ensuring sensitive data is being opened by the intended recipient is a central concern. Even if a company’s system and information are secure, there is no guarantee that the recipient’s email inbox hasn’t been compromised.

The Trustifi Difference

In response to this problem, Trustifi integrates two-factor authentication directly into the receipt process. This additional step is streamlined and simple, yet crucial for verifying that sensitive information is only being accessed by authorized individuals.

It works like this: anytime an encrypted email is sent with Trustifi, the intended recipient must authenticate their identity in one of three ways pre-selected by the sender.

The primary option is through the use of an SMS authentication code that is sent via text message.  When the recipient receives the encrypted email, it will prompt them to enter the SMS code that has been sent to their mobile device. Upon providing the verification code, the email will open and allow them to send an encrypted reply directly from the same screen.

If the recipient doesn’t have a cell phone number, or it is not known, a shared password can be used. If the recipient doesn’t remember the password right away, a hint will be provided.

The third option sends the recipient a separate email message containing their PIN code. When the encrypted email is delivered, the recipient must enter the separately sent PIN. This option ensures that any regulatory requirements for data protection have been met.

Core Benefits

The main benefit two-factor authentication provides is verification of the recipient. It does no good to go to great lengths to protect the contents of a message only to have it accessed by the wrong person. Trustifi’s two-factor authentication feature offers another layer of security to ensure that every email is opened by the intended recipient.

Email accounts can be compromised, but it is exceedingly unlikely that an email and cell phone would be compromised at the same time. Two-factor authentication utilizes multiple channels for identify verification so even if a recipient’s email account is compromised, sensitive data won’t end up in the wrong hands.


Trustifi’s two-factor authentication feature makes it the ideal email encryption platform for industries that have a regulatory requirement to protect sensitive personal data. This compliance requirement is especially salient for individuals and organizations working in the healthcare sector, financial industry, or who represent clients for legal matters. Individuals and organizations in the real estate industry, such as mortgage brokers also frequently communicate with clients over an email requesting documents that contain personally identifiable information (PII).

Each of these industries and many others benefits greatly from the added security that the second layer of identity verification provides. Trustifi’s two-factor authentication feature offers greater assurance that your sensitive data isn’t ending up in the wrong hands, and isn’t being accessed by malicious actors.

Why It Matters

The primary purpose of choosing an email encryption platform like Trustifi is to harden sensitive data while it is in-transit, making it more difficult for malicious actors to access. Two-factor authentication builds on this with an extra layer of security by offering three different methods to verify the recipient's identity one final time before they open an encrypted email.

Taken together, Trustifi’s advanced encryption and two-factor authentication are two of the most secure ways available to transmit sensitive data. With Trustifi, users can rest assured that they have comprehensive inbound and outbound protection from unwanted access to sensitive data.
