# Secrets

> Write-only values referenced by name from connector configs.

Defined in `api/ingestion/v1/secrets.proto`. Secrets back the `FieldSecret`
config field type (see [Writing a
source](/pages/connectors/building-a-connector/writing-a-source)) — stored
encrypted (see `ENCRYPTION_KEY` in [Configuration](/pages/guides/deployment/configuration))
and referenced by name from a connection or pipeline config rather than
inlined.

## RPCs

| RPC            | Purpose              |
| -------------- | -------------------- |
| `PutSecret`    | Write a secret value |
| `DeleteSecret` | Delete a secret      |

There's no `GetSecret` — secrets are write-only over the API by design.
