DCS Instance Passwords

Passwords can be configured to control access to your DCS instances, ensuring the security of your data.

Hide the password when using redis-cli.
If the -a <password> option is used in redis-cli in Linux, the password is prone to leakage because it is logged and kept in the history. You are advised not to use -a <password> when running commands in redis-cli. After connecting to Redis, run the auth command to complete authentication as shown in the following example:
```
$ redis-cli -h 192.168.0.148 -p 6379
redis 192.168.0.148:6379>auth yourPassword
OK
redis 192.168.0.148:6379>
```
Use interactive password authentication or switch between users with different permissions.
If the script involves DCS instance access, use interactive password authentication. To enable automatic script execution, manage the script as another user and authorize execution using sudo.
Use an encryption module in your application to encrypt the password.
