What are FusionAuth and Logto?
FusionAuth is a complete authentication system that manages who can access your application and what they can do. You can install it on your own computer, your company servers, or use their cloud service. This flexibility makes it different from most authentication tools that force you to use only their cloud.
The platform supports all modern login methods - traditional passwords, passwordless access, social media logins, and biometric authentication like fingerprints. It follows industry standards like OAuth2, OpenID Connect, and SAML, meaning it works smoothly with other software.
There is a free version with all core features, and paid plans add extra security, support, and cloud hosting. The free version has no user limits, making it suitable for projects of any size.
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.
