Password-Free Access
最后更新时间：2026-02-04 15:29:51
Scenarios
Storage Engine Redis/Valkey Edition supports two authentication methods: password-based access and password-free access. Users can choose flexibly based on their business security requirements.
Password Authentication: suitable for production environments with high security requirements, ensuring data access security through password authentication.
Password-Free Authentication: suitable for secure and controllable private network environments (such as the internal test environment of a VPC), simplifying the connection process.
Note:
For the sake of data security, you are not recommended to enable password-free access.
After password-free access is enabled, you are recommended to limit the number of accessing servers using a security group.
Memcached Edition only supports password-free access and does not support password authentication or creating new accounts.
Differences in Password-Free Access
The password-free authentication method of TencentDB for Redis differs from that of the Redis Community Edition:
Scenario | TencentDB for Redis® | Redis Community Edition |
After password-free access is enabled, the password in the access parameters is not empty. | Verification failed. | Verification succeeded. |
