+ * `YDB_ANONYMOUS_CREDENTIALS="1"` — used for authenticate with anonymous access. Anonymous access needs for connect to testing YDB installation
+ * `YDB_METADATA_CREDENTIALS="1"` — used metadata service for authenticate to YDB from yandex cloud virtual machine or from yandex function
+ * `YDB_ACCESS_TOKEN_CREDENTIALS=<access_token>` — used for authenticate to YDB with short-life access token. For example, access token may be IAM token
+ * `YDB_CONNECTION_STRING="grpcs://endpoint/?database=database"`
