# API keys

One key authenticates the [REST API](https://powergpu.ai/api), the [CLI](https://powergpu.ai/cli) and the [Python SDK](https://powergpu.ai/sdk). Keys act with your account's full permissions — treat them like the balance they can spend.

## Create a key

**Console → API keys → New key.** Give it a label you will recognise in an incident ("laptop-cli", "ci-runner"). The key — format pg_live_ + 40 hex characters — is shown *once*: we store only a SHA-256 hash, so it cannot be re-displayed. Lost key = revoke + new key.

## Use it

*the same key everywhere*

```
# REST
curl -H "Authorization: Bearer pg_live_…" https://powergpu.ai/v1/instances

# CLI
export POWERGPU_API_KEY=pg_live_…
powergpu list

# Python
client = powergpu.Client()          # reads POWERGPU_API_KEY
```

## Key hygiene

- **One key per consumer** — a leaked CI key then revokes without breaking your laptop.
- **Environment, not code** — POWERGPU_API_KEY in your secret store; never commit a key. If a key lands in a public repo, revoke it first, clean git history second.
- **Last-used tracking** — the keys page shows when each key last authenticated; prune the stale ones.
- **Rotation** — create the new key, roll consumers, revoke the old. Both stay valid during the overlap, so rotation is zero-downtime.

## Revocation

Deleting a key invalidates it within seconds platform-wide. Running instances are unaffected — keys gate the management plane, not the workloads.

Changing your account password signs out browser sessions but does *not* touch API keys — revoke those explicitly if the account may be compromised.
