SMS Two-Factor Authentication (2FA)
Add an extra security layer to your application logins and transaction processes using iSMS OTP-based 2FA — blocking bots, phishing attacks, and unauthorised access automatically.
Why 2FA Works — By the Numbers
According to Google Security Blog research, SMS-based 2FA codes sent to a user's phone deliver significant protection against the most common attack types.
What is Two-Factor Authentication (2FA)?
2FA is a higher security level to verify users for sensitive tasks — such as logging into an online bank account or completing a payment. With an extra security layer, it becomes significantly harder for hackers to access your users' sensitive data, even if they have the password.
The 2FA Protection Wall
Two-factor authentication acts as a protection wall between your system and malicious actors. Since OTP codes cannot be replicated and expire after a short window, it becomes extremely difficult for hackers to break into your application — even with stolen credentials.
Alleviate Your Users' Security Risk
To reduce the high risk of security breaches, iSMS provides 2FA services that add an extra layer of protection to your application's logins and transaction processes — seamlessly integrated via API.
iSMS 2FA Benefits
Integrating iSMS 2FA into your application improves security while lowering operational costs — you only need a small team to maintain your application's authentication process. Our technical team is available daily to support your integration and ongoing operations.
How Does iSMS 2FA Work?
iSMS uses our core One-Time Password (OTP) method to verify every application user's identity. The OTP is generated uniquely for each request and cannot be replicated — making it impossible for hackers to guess or reuse an old code to break into your system.
Integrate 2FA into Your Application
iSMS provides a complete 2FA API that makes it simple to add SMS OTP authentication to any website or application. See the full API documentation for integration code and parameters.
