Canonical: https://creds.id/

creds.id is a verifiable link-in-bio page. Claim creds.id/@you, add your links and share one page. The whole page is signed by your own key and checked in the visitor's browser, so anyone can confirm it is really yours on the spot: no install, no account.

## Key facts

- Category: verifiable link-in-bio page, a Linktree-style page of your links whose identity claims anyone can check.
- Address: creds.id/@yourname, 3 to 30 lowercase letters or digits. Share it as a link or a QR code.
- Signing: your key signs the whole page; change one character and the signature no longer matches.
- Checking: the visitor's browser does the check. Viewers need no app and no account.
- Account binding: your @name points to your account and your signed page points back. Only when both hold does the link get a check; a claim that is not bound both ways is marked Declared, and other links stay plain links.
- Identity map: X, Bluesky, Instagram, YouTube, GitHub and your own website.
- Sign-up: with a passkey (Apple or Google); no password.
- Phone app: iPhone and Android. The store listings still read "Solid(ar)ity - P2P Connection" while the app becomes creds.
- Made by Solid(ar)ity; the source is open on GitHub. The site is in English and Traditional Chinese.
- creds.id is not a social network and not a crypto token, and it never calls a social link verified unless the account points back to the page.

## FAQ

### What is creds.id?

creds.id is a verifiable link-in-bio page. You claim creds.id/@you, add your links and share one page. Your key signs the whole page and the visitor's browser checks it, so anyone can confirm the page and its accounts are really yours.

### How is creds.id different from Linktree?

A link-in-bio page lists your links; creds.id also proves them. The page is signed by your own key, each account it shows is bound both ways to your @name, and every check on the page opens to show how it was verified.

### Do visitors need an app or an account to check a page?

No. The browser that opens the page does the check, with no install and no account.

### How does the verification work?

Your key signs the whole page, so changing one character breaks the signature. Your @name points to your account and the account points back to your signed page; only when both hold does the link get a check.

### What does "Declared" mean on a page?

Declared marks an identity the owner has only claimed, one that is not yet bound both ways. Other links stay plain links and are never called verified.

### How do I make my page?

Claim a name (creds.id/@you, 3 to 30 lowercase letters or digits), add your links in the order you choose, then share the link or show the QR code. You sign up with a passkey, so there is no password.

### Is there a phone app?

Yes, for iPhone and Android. The store listings still read "Solid(ar)ity - P2P Connection" while the app becomes creds.

## 常見問題（繁體中文）

### creds.id 是什麼？

creds.id 是可驗證的個人連結頁（link in bio）。認領 creds.id/@你的名字、放上連結，分享一頁就好。整頁由你的金鑰簽章、在訪客的瀏覽器裡當場查驗，任何人都能確認這一頁和上面的帳號真的是你的。

### creds.id 和 Linktree 有什麼不同？

一般的連結頁只列出連結；creds.id 還能證明它們。整頁由你自己的金鑰簽章，頁面上的每個帳號都和你的 @名字雙向綁定，每個綠勾都能點開看它怎麼被驗證。

### 訪客需要安裝 App 或註冊帳號才能查驗嗎？

不需要。打開頁面的瀏覽器就會完成查驗，不用安裝、不用帳號。

### 驗證是怎麼運作的？

你的金鑰簽署整頁，改動任何一個字簽章就對不上。你的 @名字指向你的帳號，帳號也指回你簽過的頁面；兩邊都成立，連結才會打勾。

### 頁面上的「已宣稱」是什麼意思？

「已宣稱」標示的是擁有者只宣稱、還沒有雙向綁定的身分。其他連結維持一般連結，絕不會被標成已驗證。

### 怎麼做出我的頁面？

認領一個名字（creds.id/@你，3 到 30 個小寫英文字母或數字），照你想要的順序放上連結，然後分享連結或出示 QR Code。註冊用通行密鑰（Passkey），不需要密碼。

### 有手機 App 嗎？

有，支援 iPhone 和 Android。商店上的名稱目前仍是「Solid(ar)ity - P2P Connection」，App 正在改名為 creds。
