# Identify InfluxDB OSS v2 version

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

#### 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.

#### Identify your InfluxDB version

If you are unsure which InfluxDB product you are using, use our interactive version detector to help identify it:

[Detect my InfluxDB version](#)

## 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)

2. Answer questions about your setup:
    -   License type (paid or free)
    -   Hosting model (cloud or self-hosted)
    -   Server age
    -   Query language preferences
3. Get product recommendations based on your answers
