Your token stays in this browser tab and is sent only to the server below.
A read-scoped API token lets you browse mail. To compose and reply, add a send-scoped token, or paste one dual-cap identity token (read and send) in the read field; send falls back to it when the send field is empty. Tokens are kept in sessionStorage for this tab only and are never sent anywhere but the server you name.
