How do I apply for security credentials for TencentDB for MongoDB?
Before using the cloud API for the first time, you need to apply for security credentials on the Tencent Cloud console. Security credentials include SecretId and SecretKey:
SecretId: used to identify the API caller.
SecretKey: used to encrypt the signature string and server-side authentication signature string.
Notes:
API key is very important for creating TencentCloud API requests. With TencentCloud APIs, you can access and manage the resources in your Tencent Cloud account. For security reasons, store your keys safely and rotate them regularly (be sure to delete the old key when a new one is created). For more information, please see Signature Method.
What are the restrictions on using the MongoDB username?
TencentDB for MongoDB has a built-in default user mongouser, which uses SCRAM-SHA-1 authentication. The role is readWriteAnyDatabase+dbAdmin, meaning you can use this default user to read and write any database, but it does not have permissions for high-risk operations.
Instances of version 3.2 support another built-in user rwuser, which uses MONGODB-CR authentication. This authentication method has been deprecated by the official, so it is recommended to use mongouser to connect to the database.
