Authentication - TinyCloud

TinyCloud sign-in is SIWE-based. This page helps you pick the right path without mixing browser, backend, and delegation-only flows.

Choose Your Path

Intent	Go here
Browser app with wallet sign-in	Web sign-in
Automated, agent-run, or CI browser test	Automated OpenKey + TinyCloud E2E testing
Node backend that owns a space	Node sign-in
Node process that only receives delegations	Node sign-in
SDK defaults and exact method names	Web SDK reference and Node SDK reference

What This Page Covers

TinyCloud uses SIWE for the sign-in boundary.
TinyCloudWeb is the browser entry point.
TinyCloudNode is the backend entry point.
OpenKey can be the signer for TinyCloud sign-in, but OpenKey OAuth is a separate flow.

Keep OpenKey references scoped to TinyCloud sign-in support on this page. Use the OpenKey docs for the widget and OAuth flow itself.

When To Split the Journey

Use the Web page when you need a wallet popup and browser session restore. Use the Node page when you need a private-key-backed backend or a session-only consumer of received delegations.
