Transakt is an app developed by Entersekt to bring banking-grade two-factor authentication to your mobile device. Transakt works with LastPass to enable you to authenticate your login by responding to a simple Accept or Reject prompt directly on your mobile phone or tablet. Transakt protects you against threats such as phishing, man-in-the-middle, man-in the-browser, and replay attacks. It’s free to install and a snap to configure for use with LastPass.
