# Airhouse

> Oxygen's managed warehouse and connector, with ephemeral credentials

**Airhouse** is Oxygen's first-class warehouse and connector — where your data
lands and is queried from. Its defining trait is **ephemeral credentials**:
workspaces mint short-lived credentials from a service account on demand, so
there's no standing secret to store or rotate.

## When to use Airhouse

Use Airhouse when you want Oxygen to manage the warehouse for you — no
provisioning, no credential rotation, no separate account to wire up.

If you already have a warehouse, you don't need Airhouse. Oxygen
[connects to your own](/docs/guide/build/connect-data) — BigQuery, Snowflake,
Postgres, Redshift, ClickHouse, DuckDB, MotherDuck, MySQL, and more — and the
[semantic model](/docs/guide/build/semantic-model/simple-model) compiles the same way
regardless of where the data lives.

## Credentials

Unlike a traditional warehouse connection, Airhouse has **no long-lived key**.
Each workspace mints short-lived credentials from a service account when it needs
them, so there's nothing to rotate and no standing secret to leak.
