# Authentication

> Authentication for the Upstash Developer API

The Upstash API requires API keys to authenticate requests. You can view and
manage API keys at the Upstash Console.

Upstash API uses HTTP Basic authentication. You should pass `EMAIL` and
`API_KEY` as basic authentication username and password respectively.

With a client such as `curl`, you can pass your credentials with the `-u`
option, as the following example shows:

```curl theme={"system"}
curl https://api.upstash.com/v2/redis/databases -u EMAIL:API_KEY
```

Replace `EMAIL` and `API_KEY` with your email and API key.
