```
You can find your Account ID and AccessKey ID in the Overview page of the Function Compute console under the Common Information section.
Serverless Devs also supports adding keys through commands. For example, run the following command to configure Alibaba Cloud key information:
```
s config add --AccessKeyID yourAccessKeyID --AccessKeySecret  yourAccessKeySecret --AccountID 188077086902**** --access ***
```
Important
To manage multiple keys easily, Serverless Devs supports multi-key management. When configuring a key, assign it an alias (aliasName). Then, specify a particular key by its alias when using it for specific tasks. Examples include the following:
- Separating environments using different aliases for different accounts and deploying resources under different accounts—for example, using Account A for production and Account B for staging.
- Applying access control to keys so that each key has only the permissions needed for its assigned task. Examples include the following:
  - Configuring a key with the alias website-access for website deployment only.
  - Configuring a key with the alias fc-access for function deployment only.
