Digital identity paired with 2FA is a more secure authentication method

Two-factor authentication significantly decreases the risk of hackers accessing online accounts, blocking 96% of bulk phishing attacks. When digital identity and 2FA are combined, you receive a secure authentication product that is built to scale globally. Authentication factors include one-time password sent to a mobile device, phone number reputation scoring, subscriber status and more.

Two-factor + Digital Identity Protect Against:

Account takeover
Fraudulent transactions
Unauthorized account access
Account hijacking
