Sign in to access your cloud library. EPUB contents are encrypted in your browser before upload. Your randomly generated account key is stored in your private bucket and fetched after sign-in, so there is no separate passphrase.
Sign in to your cloud account, then upload any local .epub file or generate a sample book to test the reader.
