Two-Factor Authentication for Business

The security of user accounts and sensitive information has become a major priority as cyber threats become increasingly sophisticated and need robust solutions to prevent unwanted entry attempts.

Two-factor authentication (2FA) has evolved as an effective and proven means of improving security by adding a layer of protection to the usual username-password combination. At Esendex, we take pride in providing a comprehensive and cutting-edge Two-Factor Authentication Service that strengthens your security measures and improves the user experience.

An Overview of Two-Factor Authentication (2FA)

Two-factor authentication (2FA) is a security feature that requires users to provide two unique forms of identification before accessing their accounts or sensitive information.

While the typical username-password combination is subject to hacking and phishing assaults, 2FA adds an extra layer of security, making it far more difficult for unauthorized users to access.

Numerous Authentication Channels

One of the key benefits of our Two-Factor Authentication Service is its adaptability. We understand that different users have varied preferences and levels of comfort with different login methods. We provide a variety of authentication routes to meet a wide range of user requirements:

Short Message Service

SMS authentication is one of the most popular 2FA options. It entails delivering a one-time code to the user’s registered cellphone number through text message, which they must enter to obtain access to their account.

Voice Calls

SMS OTP verification is the most reliable method of authentication. It’s one of the only ways to ensure the user can access a system or account, reducing the risk of fraud and unauthorized access to critical information.


Users can choose to get a one-time code through email for a seamless and speedy authentication experience, which they can then use to log in securely.

Push Notifications

Push notifications provide a quick and safe means of authentication. Users are prompted to authorize or refuse access via a notice on their registered device.


WhatsApp, one of the most popular messaging programs in the world, provides users with a familiar and quick authentication mechanism.

TOTP (Time-Based One-Time Passwords)

TOTP generates time-sensitive codes using mobile apps such as Google Authenticator or Authy, providing an additional layer of protection to the authentication process.

Messages Approved by Global Carriers for Seamless Delivery

The timely delivery of authentication messages is critical for the effectiveness of any two-factor authentication system. That’s why we offer carrier-approved message templates to eliminate any carrier filtering or restricting. This ensures that our communications are delivered following the highest standards, allowing users to finish the authentication procedure easily.

Recognizing the global nature of most businesses, our platform includes automatic translation capabilities, allowing you to communicate in many languages while adhering to international rules.

Let’s start sending, together.
