# Wasabi

ExpanDrive connects to Wasabi buckets using an access key ID and secret access key.

## Connection Parameters

The connection settings identify the Wasabi endpoint, credentials, and optional bucket to mount.

### Server

This is the address at which the service can be reached. Wasabi provides different addresses [depending on your storage region](https://docs.wasabi.com/docs/what-are-the-service-urls-for-wasabi-s-different-storage-regions). Choose the service URL that matches your bucket location.

### Access Key

Access keys are used to make secure requests to the Wasabi service API. The Wasabi Console allows you to [define access keys](https://docs.wasabi.com/docs/creating-a-user-account-and-access-key#assigning-an-access-key) for a user.

An account can have only two access keys per user (two per root account and two per sub-user).

The access key and secret key authenticate as a pair. Either one alone is not useful; together they grant full access to your S3 resources.

### Secret Key

The secret key is your private authentication key that pairs with your access key. This is like a password.

When you save the connection, ExpanDrive stores the secret key in your operating system's [credential store](/security.md#credential-storage).

### Bucket

This field lets you restrict which bucket the connection can access. See [Bucket-Level Organization](/connections/object-storage/amazon-s3.md#bucket-level-organization) for more information.

If your credentials do not have access to list the buckets in your account, provide the bucket name in your connection parameters.

### Nickname

The nickname identifies the connection and appears as the volume label on the mounted drive.
