Safeguarding billions of login transactions each month, Auth0 delivers convenience, privacy, and security so customers can focus on innovation. Auth0 is part of Okta, The World’s Identity Company™. \n\nAuth0 lets you quickly integrate authentication and authorization for web, mobile, and legacy applications, with new Fine Grained Authorization (FGA) that goes beyond role-based access control.\n\nAuthenticate users across all applications with a customized, secure, and standards-based single login. Universal Login connects users to a central authorization server. Credentials aren’t transferred across sources, which boosts security and protects against phishing and credential stuffing attacks. OAuth 2.0 recommends that only external user agents (like the browser) be used by native applications for authentication flows. Auth0’s Universal Login achieves this while also enabling SSO.","image":"https://gdm-catalog-fmapi-prod.imgix.net/ProductScreenshot/05cf5c9e-c31d-4d99-bb6a-cbcfb4517350.png","url":"https://www.capterra.co.uk/software/154900/auth0","@type":"SoftwareApplication","@id":"https://www.capterra.co.uk/software/154900/auth0#software","applicationCategory":"BusinessApplication","publisher":{"@id":"https://www.capterra.co.uk/#organization"},"aggregateRating":{"@type":"AggregateRating","bestRating":5,"ratingCount":145,"ratingValue":4.7},"offers":{"price":"0","@type":"Offer","priceCurrency":"USD"},"operatingSystem":"Cloud, Android, Platform ios, Platform ipad"},{"name":"Firebase","description":"Firebase is a platform that provides a suite of tools and services designed to help developers build, improve, and grow applications across various platforms, including iOS, Android, and the web.
