Current Challenges in User Access

• Long-Term Data Ownership: Using major platforms for login often means surrendering control of your data indefinitely. Users want clarity on who owns their data and how it’s stored and managed over time.
• Fragmented Digital Identities: With accounts scattered across platforms like Google, Facebook, LinkedIn, and more, managing logins becomes complex. People need a unified, secure way to access apps without losing track of their identities.
• I don’t want to be forced to share my real identity: Some users prefer to log in with minimal details, without needing to disclose personal information like email, phone number, or full name.
• What happens to my accounts when I die? Many are concerned about the future of their digital identity. They want clear control over how their accounts are managed if they’re no longer around, protecting their digital legacy.

Roadmap

Ready and Available ✅

• Multi-Provider Authentication: Log in via Google, Facebook, Apple, GitHub, MetaMask, and more.
• Zero Tracking: No data tracking—user information remains private.
• Two-Factor Authentication (2FA): Secure logins with SMS, email, or authenticator apps.
• Recent Activity Review: Monitor and review account activity for unauthorized access.
• Self-Managed Login History: View, download, or delete login history to monitor and manage account access.
• Seamless Developer Integration: Quick setup with minimal code for easy logins.

In Progress 🚧

• End-to-End Encryption: Encrypt user data for enhanced security.
• Trusted Devices Management: Manage devices connected to your account.

• Plan Your Digital Legacy: Set up account management for when you can no longer access it.
• Autofill Support: Autofill passwords and payment info for faster logins.
• Eartho Pay: Integrate payments securely alongside authentication.
• Customizable UI: Tailor Eartho’s login widget to fit your brand.
• Biometric Authentication: Fingerprint and facial recognition for secure access.
• Anonymous Login: Protect identities with anonymous access.
• Advanced Analytics Dashboard: Gain insights into account activity and data usage.
• Granular Privacy Controls: Set specific data permissions for apps.
• Multi-Account Management: Easily switch between multiple accounts.
• Enhanced Offline Access: Authenticate even without internet connectivity.

Future

• Browser Extension: Autofill, and more.
• Eartho One Tap: Users are prompted to create an account with a dialog that's inline with your app's content, so they're never taken out of context by a sign-up screen.

How It Works

Eartho serves as a privacy-focused layer between users and major authentication providers like Google, Facebook, and others. When users log in using Eartho, they can still choose popular sign-in options such as Google Sign-In or Facebook Login, but with a critical difference: Big Tech companies will no longer have access to your users’ login services list.

By wrapping major sign-in services, Eartho provides the best of both worlds: the convenience of popular authentication providers and the security of true privacy for users, ensuring that no personal data leaks to third-party companies.

Why Eartho?

In today’s digital age, privacy is paramount. Most single sign-on (SSO) providers collect data from users and track their online activity. Eartho solves this problem by offering a sign-in solution that ensures users’ privacy remains intact.

Developers can integrate Eartho with a few lines of code and provide users with:

• Secure login options
• Control over what data they share and with whom
• A unified account management system with multiple login methods
• Protection from Big Tech tracking and surveillance

Eartho is built for developers who care about privacy and security, but don't want to compromise on ease of use.

Tech Stack ⚙️

• Backend: Next.js API for authentication + Node.js to manage overall data and endpoints

• Frontend: Next.js (React)

• Database: Firestore(Should be replaced)

• Cloud: Google Cloud Platform (GCP)

• Authentication: OAuth 2.0, JWT

• Auth.js: Our one module use auth.js

       redirect_uri: 'YOUR_REDIRECT_URI'
   });

3. Add Login and Logout Features
   Implement login and logout functionality to allow users to sign in or out securely:

   function login() {
       eartho.connectWithPopup().then(result => {
           console.log('Logged in as:', result.token);
           console.log('Logged in as:', result.user);

Frequently Asked Questions (FAQ)

Why should I trust you?

We're committed to being as transparent as possible. We use well-established, widely adopted open-source libraries that have been trusted by millions of developers. Our team has years of experience in the industry, and we’re dedicated to building a platform that puts users' privacy and security first.

We understand this is a new project, and we’re constantly improving. Our code is open for anyone to review, contribute to, or suggest improvements. While it’s early days for Eartho, our goal is to continually evolve and provide a safe, privacy-first solution for managing digital access.

Disclaimer: As this is a growing project, we’re always open to feedback and making things better over time.

Who is behind Eartho?

Hey! I'm Dvir Daniel, the creator of Eartho. I've been working in the IT industry for almost 10 years as a software engineer. Eartho started as my personal project with the goal to offer a privacy-first, open-source alternative to Google Sign-In. Right now, it's just me and a few friends helping out here and there. It's still early days for the project, but we’re improving it step by step and being as transparent as possible. Excited to have you join us on this journey!

Why does your privacy policy say you collect so much information?

We know our privacy policy might seem a bit overwhelming, and we get that. The reason it’s so detailed is because we're a new project, and we want to cover ourselves legally while we’re still figuring things out and improving. We’re being cautious to make sure we don’t miss anything and to leave room for mistakes as we grow.

Our goal isn’t to collect unnecessary data or misuse your information. In fact, we're working hard to protect your privacy. But since we're still new and evolving, we’ve put everything in the policy to be safe and transparent with you. As the project develops, we’ll likely refine it and make things clearer over time.

We’re committed to making privacy a priority, and this is just one step in that direction.

How is Eartho different from other authentication services like Auth0 or Keycloak?

Eartho is designed with the user in mind, and not for developers, offering features like multiple identities, privacy-first payments, and the ability to plan your digital legacy. Unlike developer-focused tools, Eartho provides users with control over their access and personal data.

Developers add us as sign in option to their existing solution and they can can manage their users in Keycloak if they want. we are like Google/Facebook/Apple sign in

Why should I trust Eartho with my data over Big Tech like Google/Facebook/Apple ?

Big Tech may collect data as part of their larger ecosystem, but for Eartho, access and privacy are our mission. While for them it's just another piece of the puzzle, for us, it’s the focus. We’re committed to being more convenient and advanced when it comes to managing access, giving you full control over your data and logins. Being open-source means transparency, and with Eartho, you always know where your information is and how it's used.
