This page documents an earlier version of InfluxDB OSS.[InfluxDB 3 Core](/influxdb3/core/) is the latest stable version.

> [!Important]
> #### API token hashing is enabled by default in InfluxDB OSS 2.9.0
>
> Stronger token security: tokens are stored as hashes on disk, so a
> copy of the database file doesn’t expose usable tokens. Existing
> tokens are hashed on first startup and the original strings can’t
> be recovered afterward — **capture any plaintext tokens you still
> need before you upgrade**.

> For more information, see [Token hashing](/influxdb/v2/admin/tokens/#token-hashing).

Identifying which InfluxDB product and version you’re using is essential for accessing the correct documentation, troubleshooting issues, and planning upgrades.

## Quick detection methods

### InfluxDB OSS v2 detection

Check the version using `influxd`:

```bash
influxd version
```

Query the `/health` endpoint and extract the version:

```bash
curl -s http://localhost:8086/health | jq -r '.version'
```

The InfluxDB UI displays the version:

* On the login page
* In the right column of the main landing page
* In the user menu dropdown

For more details, see [How can I identify my InfluxDB version?](/influxdb/v2/reference/faq/#administration-1)
