“PropelAuth offers seamless management of user login/logout states both in the browser extension and on the main webpage—an essential feature for the functionality of the Cognify browser extension. I tried Clerk and Kinde, but lacked simple integration options for browser extension authentication, PropelAuth provided an effortlessly smooth solution that perfectly met the business needs”
