This topic describes how to create an SSH key pair in the ECS console. After a key
pair is created, you must immediately download and securely lock its private key away.
To log on to an ECS instance that is bound with an SSH key pair, you must have the
private key. You can have a maximum of 500 key pairs in a region.
Procedure
- Log on to the ECS console.
- In the left-side navigation pane, choose .

You can select one of the following methods of creating SSH key pairs: We recommend
that you select Auto-create and save the private key in a timely manner.
- Auto-create: The system automatically creates a key pair for you. Download the private key immediately
after it is created. You cannot download the private key at any time afterwards.

Result
After the key pair is created, your browser automatically downloads the private key
file (<key pair name>.pem) to your local computer.
Notice Private key files are automatically downloaded to the local computer only when the
key pairs are created. Private key files are not saved in the ECS console. Private
key files cannot be recovered once lost. We recommend that you securely lock away
your private key files.
