You can obtain the ID and AccessKey pair of your Alibaba Cloud account in the References section of the Overview page in the Function Compute console.
Serverless Devs also allows you to add keys by running commands. For example, you can run the following command to add an AccessKey pair:
```
s config add --AccessKeyID LTAI4G4cwJkK4Rza6xd9**** --AccessKeySecret  eCc0GxSpzfq1DVspnqqd6nmYNN**** --AccountID 188077086902**** --access ***
```
Notice Serverless Devs allows you to manage multiple keys. When you add a key, you can specify the feature of the key by setting the aliasName parameter. Scenarios:
- You want to isolate environments. In this case, you can set different aliases for the keys of different accounts and deploy resources by account. For example, you can use Account A in the production environment and Account B in the staging environment.
- You want to manage permissions by key. In this case, you can grant different permissions to different keys. Examples:
  
  Set the website-access alias for a key that is used for website deployment.
  
  Set the fc-access alias for a key that is used for function deployment.
