SMS 2FA Security

Mitigate risk and protect user data with SMS Two-Factor Authentication

2 Factor Authentication

2FA (Dual Factor Authentication) is a verification process for securing account logins for websites, software, or applications. These codes can be programmed to be time sensitive, and can help validate a user’s identity when attempting to login.

SMS OTP (One-Time Passwords)

In an effort to secure their accounts, users often forget complicated passwords. Grant users access with one-time SMS passwords that have single-use and time expirations.

Digital Security

Data breaches and fraud aren’t going anywhere, and cyber criminals are getting smarter. Add another layer to your digital security with SMS, and keep criminals out of users’ accounts.

Fraud & Spam Prevention

Credit card, transaction, and identity fraud are on the rise. Protect your business and customer data by adding our mass text notification system into your security process.
