Our patented Two-Factor Authentication (2FA) technology helps you protect against fraud, build trust, and increase conversions across multiple channels. Make customers feel secure with verify. Plus, you’ll only pay for successful verifications.
Verify now gives customers the ability to generate and manage their own PIN codes and even customise the failover sequence to other channels such as sms, voice and even WhatsApp and Facebook Messenger as they become available.
Verify users by reaching their mobile device with SMS or Voice Codes.

A single API provides the full 2FA solution, from authentication management to message automation, spanning SMS and Voice.

Unlike other 2FA methods that may require special hardware or an authenticator app, our solution works with any phone number.

Just give us a phone number and we’ll take care of the rest. We generate the codes, localise, use the fastest channel available, even fall back from SMS to voice when needed.

Pay only for successful conversions or a flat monthly fee for frequent logins.
Ensure security by delivering time-limited, single-use authorisation codes to known numbers.
Replace static passwords with single use codes sent over SMS, Voice or Push. Let users gain instant and secure access to your app with just their phone. Works reliably with any type of phone line anywhere in the world with a single API.
Minimise fraud while delivering a friendly user experience with automatic fraud detection and trigger step-up authentication when needed.
Use up to date intelligence on phone numbers to detect potentially fraudulent transactions. Step-up authentication only for those numbers suspected of being fraudulent.
Eliminate spam more effectively. Block bot-nets and bulk account creation with phone verification for new users.
Phone verification prevents bulk account creation more effectively than captchas or social logins. Improve the customer experience by minimising the personal information being shared and provide a nearly frictionless registration experience for mobile users.
