      Article Summary

      S3 Browser is a freeware Windows Client for S3-compatible cloud services such as Backblaze B2 Cloud Storage.

      Enable Backblaze B2

      Before you begin: You must have a Backblaze B2 Cloud Storage account. You can sign up here. If you already have a Backblaze account and the left navigation menu contains a B2 Cloud Storage section, your account is already enabled for Backblaze B2.

      1. Sign in to your Backblaze account.
      2. In the left navigation menu under Account, click My Settings.
      3. Under Enabled Products, select the checkbox to enable B2 Cloud Storage.
      4. Review the Terms and Conditions, and click OK to accept them. 

      Create a Bucket

      You can use an existing bucket, or you can create a new one. You will need the value from the Endpoint field for the S3 Browser configuration.

      1. Sign in to your Backblaze account.
      2. In the left navigation menu under B2 Cloud Storage, click Buckets.
      3. Click Create a Bucket.
      4. Enter a name for your bucket.
        Bucket names must be at least six characters and globally unique. A message is displayed if your bucket name is already in use.
      5. Select a privacy setting: Private or Public.
        Files that are in a private bucket require authentication to perform an action, for example, downloading. Public buckets do not require authentication so you can easily share files. You can change a bucket's privacy settings at any time.
      6. If applicable, enable a Backblaze B2 server-side encryption key.
      7. If applicable, enable Object Lock to restrict a file from being modified or deleted for a specified period of time.
      8. Click Create a Bucket, and copy the value that is in the Endpoint field; you may need this value for other processes.
      9. Click Lifecycle Settings to control how long to keep the files in your new bucket.

      Create an Application Key

      If you use a bucket-restricted app key, select Allow List All Bucket Names to allow the List All Bucket Names permission to work successfully with the S3-Compatible API. If you do not select this option when you create your app key, you must create a new app key and enable the required permission.

      Application keys control access to your Backblaze B2 Cloud Storage account and the buckets that are contained in your account.

      1. Sign in to your Backblaze account.
      2. In the left navigation menu under Account, click Application Keys.
      3. Click Add a New Application Key, and enter an app key name.
        You cannot search an app key by this name; therefore, app key names are not required to be globally unique. 
      4. In the Allow Access to Bucket(s) dropdown menu, select All or a specific bucket.
      5. Select your access type (for example, Read and Write).
      6. Select the optional Allow List All Bucket Names checkbox (required for the Backblaze B2 S3-compatible API List Buckets operation).
      7. Click Create New Key, and note the resulting keyID and applicationKey values.
      Note
      When you create a new app key, the response contains the actual key string, for example N2Zug0evLcHDlh_L0Z0AJhiGGdY. You can always find the keyID on this page, but for security, the applicationKey appears only once. Make sure you copy and securely save this value elsewhere.

        2. Select S3 Compatible Storage as your account type.
        3. Enter the endpoint URL that you noted in the Create a Bucket task.
        4. Enter your application key ID in the Access Key ID field.
        5. Enter your application key in the Secret Access Key field.
      3. Click Add new account.
