From the Aiven, locate your **`Service URI`**`.`

In the Lenses bootstrap UI:

1. Set the Service URI as bootstrap servers
2. Set **`SASL SSL`** as the security protocol
3. Set **`SCRAM-SHA-SHA-256`** as the security mechanism
4. Set the\*\*`jaas.conf`\*\* as the following:

```bash
org.apache.kafka.common.security.plain.PlainLoginModule required
