What are Logto and Stack Auth?
Logto is an authentication and identity management platform that handles user sign-in, permissions, and security for your applications. You can use it as a cloud service or install it on your own servers since it's open-source.
The platform supports multiple ways for users to sign in: traditional passwords, email codes, phone verification, social media accounts like Google and Facebook, or enterprise systems through Single Sign-On. It also includes advanced features like multi-factor authentication for extra security and role-based access control to manage what different users can do.
Logto works with over 30 programming languages and frameworks including React, Next.js, Vue, Python, and Go. It's trusted by companies worldwide and meets strict security standards with SOC 2 Type II certification.
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.
