# NOAUTH Authentication Required

### Symptom

The client can not connect to the database throwing an exception similar to:

```
[ioredis] Unhandled error event:
ReplyError: NOAUTH Authentication required
```

### Diagnosis

The server does not let you connect because the password is missing in your
connection parameters.

### Solution

Check your connection parameters and ensure they contain the password. Your
database's password is the **Token** shown in the
[Upstash Console](https://console.upstash.com). There is no separate password.
If you are using ioredis (Redis client) with a Redis URL, check the URL format.
ioredis requires a colon before the password:

```
rediss://default:YOUR_TOKEN@YOUR_ENDPOINT:YOUR_PORT
```

You can copy the correct connection string from the **Connect** section
(**TCP** tab) on your database page in the Upstash Console.
