What are OneLogin and Stack Auth?
OneLogin is a cloud platform that manages who can access your company's apps and data. It acts as a central hub where users log in once and gain access to all their authorized applications without needing separate passwords for each tool.
The platform includes several key capabilities: single sign-on lets users access multiple apps with one login, multi-factor authentication adds extra security layers, and automated user provisioning creates and removes accounts automatically when people join or leave your organization. OneLogin also connects with your existing directories like Active Directory or cloud systems like Workday.
Unlike traditional methods where IT teams manually manage each user's access, OneLogin automates these tasks while maintaining strong security through modern authentication methods and access policies.
Stack Auth is a complete authentication solution that handles all the complex parts of user login and management. When you add it to your application, you get ready-made login pages, account settings, password reset flows, and user dashboards without writing code for these features yourself.
The platform supports multiple ways for users to sign in, including regular passwords, social logins through Google or GitHub, magic email links, and modern passkeys using fingerprints or face recognition. It also handles advanced features like two-factor authentication for extra security, team management for business apps, and permission systems to control what different users can do.
Stack Auth is fully open-source and licensed under MIT and AGPL, meaning you can see exactly how it works and modify it if needed.
