# Generate a QR code login link for a use case

> Creates a dedicated service account for this magic link, sets its knowledge permissions to the selected assets, and returns a persistent magic token. Each POST creates a new link with its own access scope. Optional `expires_at` (ISO 8601, UTC) stops the link after that instant; omit or null for no time-based expiry. The frontend builds the URL as `{origin}/?sat={token}`. Requires update permission on the use case.
