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™. Auth0 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. Authenticate 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 enabling SSO. 1,069 Ratings Visit Website Keeper Security Keeper Security is transforming the way people and organizations around the world secure their passwords and passkeys, secrets and confidential information.

About AuthStack is a host anywhere, Enterprise-grade, Single Sign-On (SSO) and Identity Access Management (IAM) System. It assumes responsibility for logging in users to your own, and optionally third-party websites and applications. Rather than managing multiple different logins for each website and application, AuthStack centralizes your user identity management so the user only has to login once and maintain one password and profile. Integration with AuthStack requires no custom coding if your website or application already supports SAML. If SAML is not supported we provide a Connector Framework, free of charge. We can also help you integrate the Connector if required. There is also no need to migrate your existing user database(s). AuthStack bundles with a Connector Framework which can communicate with any data source, whether that's LDAP, MySQL, SOAP, REST API, etc, to check credentials from existing user databases.	About Keycard is an identity-and-access infrastructure platform built for the agent-native era, enabling developers and enterprises to securely connect AI agents, users, services, and APIs with real-time, policy-driven identity controls. It issues dynamic, ephemeral access tokens in place of static secrets and supports federated identity models to unify users, agents, and workloads under a distributed authorization framework. The platform provides drop-in SDKs for popular frameworks so developers can build agent-aware applications without becoming IAM experts. Keycard’s data model includes identity-attested agents, tasks, tools, and resources, allowing logical zones with context-aware permissions and auditability. On the policy side, security teams can define deterministic, task-based rules that enforce who (user/agent) can do what (task) on which resource under which conditions, all with full transparency.
