Bring Your Own Identity (BYOI)

About

Instead of creating separate accounts or sharing personal data with every website, BYOI allows users to authenticate using an identity that stays entirely in their browser and under their control.

No passwords.
No centralized accounts.
No tracking.

🚀 How it works

BYOI works together with the BYOI SDK, which websites can integrate to support decentralized sign-in.

For users
✦ Your identity is created and stored locally in your browser
✦ Identity requests always require explicit user approval
✦ Nothing is sent to external servers by default
✦ You can use the same identity across multiple supported websites

For websites
✦ Websites integrate the BYOI SDK
✦ When a user chooses to sign in, the site sends a request to the BYOI extension
✦ The extension prompts the user for consent
✦ Only the approved identity information is shared directly with the website

The extension remains inactive on websites that do not integrate the BYOI SDK.

🧩 Extension + SDK model
✦ The extension acts as the user’s identity wallet
✦ The SDK acts as the communication bridge for websites
✦ Websites cannot access identity data unless:
          ✔  They explicitly integrate the BYOI SDK, and
          ✔  The user explicitly approves the request

🔒 Privacy by design
✦ No user data collection
✦ No analytics or tracking
✦ No browsing history access
✦ No centralized identity provider

🌐 Open and developer-friendly
BYOI is designed as an open, developer-friendly system that makes decentralized identity easy to adopt without sacrificing user privacy or control. Websites can support BYOI without managing passwords, accounts, or sensitive user data.

📌 Summary
BYOI lets users bring their identity with them — safely, privately, and transparently — while giving websites a simple way to support modern, user-owned authentication.
