Ultra OTP is a Chrome extension developed by Thomas Girgenti. It is a companion to the Ultra OTP web app and provides users with a quick and secure way to access one-time passwords (OTPs) in their browser.

With Ultra OTP, users can easily generate and access OTPs without the need to navigate away from their browser. The extension utilizes standard Web Crypto protocols to ensure that sensitive token data, including issuers, labels, and secrets, is securely encrypted and decrypted by the client. Additionally, all data is stored in an encrypted cloud database, adding an extra layer of security.

The Ultra OTP extension is a valuable tool for those who rely on OTPs for secure authentication. It offers a convenient way to manage and access OTPs directly within the Chrome browser, providing users with a seamless and secure experience.
