This article is about how to bind and unbind SSH key pairs on the ECS management console. The editor thought it was very practical, so I shared it with you as a reference. Let's follow the editor and have a look.

Bind and unbind SSH key pair

Use restriction

Only one SSH key pair can be bound to an ECS instance.

All Linux instances of the instance specification family support SSH key pair login except for non-Ishock O optimized instances of series I.

If the ECS instance is running (Running), you need to restart the instance for the operation to take effect after binding or unbinding the SSH key pair.

If the ECS instance has been bound with a SSH key pair, the new key will automatically replace the original key when the new key pair is bound.

If the ECS instance uses password authentication, the password authentication method becomes invalid automatically after the key pair is bound.

After unbinding the key pair, you need to reset the instance password to log in to the ECS instance using password authentication.

Log in to the ECS Management console.

In the bind key pair dialog box, in the Select ECS instance bar, select the name of the ECS instance to which you want to bind the key pair, click >, and move to the selected column.

Description

Click OK to bind the key pair.
