# Adding External Buckets

OBS Browser supports the external bucket adding function.

#### Prerequisites

You have obtained the permissions to read and write the external bucket that you want to add.

For example: Account A wants to add bucket testbucket of account B. Account B must authorize account A the permission to read bucket testbucket. If account A needs to upload object to bucket testbucket, account B needs to authorize account A the permission to write the bucket. Account A is the owner of the uploaded objects, and needs to authorize account B the permission to read and write the objects.

An external bucket (version 3.0 or later) can be added only when its standard bucket policy is set to Public Read and Write.

If the standard bucket policy of an external bucket is set to Public Read and Write upon its creation, you need to manually change the standard bucket policy to Private and then change it back to Public Read and Write again, so that it can be added.

#### Procedure

1. Log in to OBS Browser.
2. Click Add Bucket on the upper left corner of the page. The Add Bucket dialog box is displayed.
3. Select Add external bucket and enter the bucket name.
