## Security model

Understand how Passport proves identity, enforces permissions, and keeps secrets inside your cloud. See [Security model](/passport/get-started/basics/security-model/).

## End-to-end flow

See how all the pieces fit together, from registering the proxy to sending an authenticated API request. See [End-to-end flow](/passport/get-started/basics/end-to-end-flow/).
