+# Resource: bitbucketserver_user_access_token
+
+Personal access tokens can be used to replace passwords over https, or to authenticate using the Bitbucket Server REST API over Basic Auth. 
+
+For git operations, you can use your personal access token as a substitute for your password.
+   
+> Note: You can only create access tokens for your user account - i.e. the one that the provisioner has been configured to authenticate with!
+> This is a restriction in the Bitbucket APIs.
+
+## Example Usage
+
+```hcl
+resource "bitbucketserver_user_access_token" "token" {
+  user        = "admin"
+  name        = "my-token"
+  permissions = ["REPO_READ", "PROJECT_ADMIN"]
+}
+```
+
+## Argument Reference
+
+* `user` - Required. Username of the user.
+* `name` - Required. Name of the access token.
+* `permissions` - Required. List of permissions to grant the access token.
+
+     * `PROJECT_READ`
+     * `PROJECT_WRITE`
+     * `PROJECT_ADMIN`
+     * `REPO_READ`
+     * `REPO_WRITE`
+     * `REPO_ADMIN`
+
+## Attribute Reference

+* `access_token` - The generated access token. Only available if token was generated on Terraform resource creation, not import/update.
+* `created_date` - When the access token was generated.
+* `last_authenticated` - When the access token was last used for authentication.
+
