Tablestore verifies user identities based on AccessKey pairs. Users who pass the verification can access Tablestore resources.
An Alibaba Cloud account can have multiple AccessKey pairs. The Tablestore resources that you can access are the same when you use different AccessKey pairs.
If you want to access Tablestore resources as a Resource Access Management (RAM) user, the RAM user must be granted the required permissions and the RAM user can access only specified Tablestore resources. For more information about how to grant permissions to a RAM user, see Use a RAM policy to grant permissions to a RAM user.
If you forget the AccessKey pair of a RAM user, you can recreate an AccessKey pair and record information about the AccessKey pair. For more information, see Create an AccessKey pair.
