You are viewing this workspace read-only. Everything here is real and live on the test network, and you are welcome to look through it. Registering receivables, selling a pool and revealing a pool passkey all need an account. Sign in or create one and you can use the whole workspace, whatever your email address.
A Loan ID plus this passkey is all anyone needs to verify a receivable in this pool on the public site, so treat it as a credential. It cannot be changed once receivables are registered: the certificate ID is derived from the Loan ID and the passkey together, so a new passkey would orphan every certificate in the pool.
