Enable or disable password-free access for an ApsaraDB for MongoDB instance

Prerequisites

• A replica set or sharded cluster instance whose database version is 4.0 (the minor version of mongodb_20190408_3.0.11 or later) or 4.2 is used. If your database engine is earlier than the required version, upgrade the instance. For more information, see Upgrade MongoDB versions and Upgrade the minor version of an ApsaraDB for MongoDB instance.
  Note

  • Standalone instances do not support the password-free access feature.
  • You can view the database engine version and the minor version on the Basic Information page in the ApsaraDB for MongoDB console.
• The network type of the instance must be VPC. If the network type is classic network, switch it to VPC. For more information, see Switch from classic network to VPC.
