# 04.16.2026 Azure Managed Identity for PostgreSQL

> Connect Phoenix to Azure Database for PostgreSQL using managed identity — no static passwords required.

**Available in arize-phoenix 14.8.0+**

Phoenix now supports Microsoft Entra managed-identity authentication when connecting to Azure Database for PostgreSQL (Flexible Server). Set two environment variables and install the `azure` extra — Phoenix handles token acquisition and refresh automatically on every new database connection.

## Setup

Install the `azure` extra to pull in `azure-identity` and `aiohttp`:

```bash theme={null}
pip install 'arize-phoenix[azure]'
```

Set the required environment variables:

```bash theme={null}
PHOENIX_POSTGRES_USE_AZURE_MANAGED_IDENTITY=true
PHOENIX_SQL_DATABASE_URL=postgresql+asyncpg://<user>@<host>/<db>
```

`PHOENIX_POSTGRES_AZURE_SCOPE` defaults to `https://ossrdbms-aad.database.windows.net/.default`. Override it only if you are running in a sovereign cloud such as Azure US Government:

```bash theme={null}
PHOENIX_POSTGRES_AZURE_SCOPE=https://ossrdbms-aad.database.usgovcloudapi.net/.default
```

## Notes

* **Mutual exclusion** — `PHOENIX_POSTGRES_USE_AZURE_MANAGED_IDENTITY` and `PHOENIX_POSTGRES_USE_AWS_IAM_AUTH` cannot both be `true`; Phoenix raises a `ValueError` at startup if both are set.
* **`PHOENIX_POSTGRES_AWS_IAM_TOKEN_LIFETIME_SECONDS` is deprecated** — the env var is now silently ignored with a startup warning. Connection pool hygiene is managed internally.
