TypingDNA Authenticator is a two-factor authentication application that provides an additional layer of security for online accounts. The product functions as a mobile security app that generates time-based one-time passwords (TOTP) for account verification. The authenticator operates through a browser extension that can capture QR codes from websites during the two-factor authentication setup process. Users can add accounts by scanning QR codes or manually entering secret keys. Once configured, the extension generates verification codes that can be automatically pasted into login forms. The product supports standard TOTP-based authentication workflows compatible with services that offer authenticator app-based two-factor authentication. Users can manage multiple accounts within the extension, with each account displaying its own verification codes. The interface allows users to modify account names and secret keys after initial setup. TypingDNA Authenticator is delivered as a browser extension and integrates with the standard two-factor authentication protocols used by major online platforms. The company has been recognized as a Sample Vendor in Gartner Hype Cycle for Digital Identity 2025.
