Cloud Login

Approve sign-ins to multiple Clouds from one installable app.

2 min read Updated 2026-09-09 #authentication#pwa#devices

Cloud Login is an installable web app for approving sign-ins to your Cloud accounts. Connect accounts from different Clouds and manage them in one place. It runs separately from the Cloud installations you connect.

Open Cloud Login

Start using it

Your Cloud administrator must first enable app sign-in and choose the authenticator address. Use the app configured by your Cloud.

  1. Open Cloud Login and choose Install app from its menu, or continue in your browser.
  2. Choose Add Cloud and set up a passkey or six-digit app PIN.
  3. On your Cloud profile, open Security → Pair a device. Scan the QR code or paste its link into Cloud Login, then compare and confirm the codes.
  4. When you start a sign-in, open Cloud Login. Compare the code shown in the request with the sign-in page, then approve or deny it.

Pair each account separately. You can add another Cloud, edit account labels, or disconnect an account through Manage accounts.

Protect and recover

One app lock protects all connected accounts on this device. A compatible passkey can use face recognition, a fingerprint, or your device code. A six-digit PIN is also available; a passkey offers stronger protection against someone guessing from copied app data.

Keep another sign-in method available. If you lose your device or reset the app, sign in to each Cloud another way, revoke the old device, and pair again.

The app can start offline after its first online visit. Pairing and approvals need a connection. Open Cloud Login to see pending requests; there are no push notifications.

Choose a guide

Cloud Login uses the public app-approval SDK and shared UI components. Each account has its own device key. The app needs no central account server and can be hosted at your own stable HTTPS address.

Connect a coding agent

The Cloud skill provides compact working instructions. MCP supplies exact current documentation when details matter.

CLI command
bunx skills add https://docs.example.com

This command installs the working instructions published by this website in the selected coding agent.

For exact, current details, also connect the MCP server through one of the agent tabs.

Installation uses the open-source Vercel Skills CLI.

The skill and MCP complement each other: the skill describes workflows, while MCP supplies current documentation.
