Generate keys
Each FI creates an RSA key pair and shares the base64 public key with Vestara.
Financial Institution Authentication Flow
This demo shows how a partner-issued JWT becomes a trusted Vestara session. Follow the steps below, then inspect the live session data captured for a downstream Financial Institution.
Sign the token
Use the provided script or existing tooling to mint an RS256 JWT containing `account_id` and optional claims.
Distribute the link
Send the FI user a secure /fi/login?token=... link so the session cookie is established instantly in their browser.
