You can use authorized keys to log in to a host with SSH. You can upload authorized keys with HTTPS PUT.

Note

Lockdown mode does not apply to root users who log in using authorized keys. When you use an authorized key file for root user authentication, root users are not prevented from accessing a host with SSH when the host is in lockdown mode.

Authorized keys allow you to authenticate remote access to a host. When users or scripts try to access a host with SSH, the key provides authentication without a password. With authorized keys you can automate authentication, which is useful when you write scripts to perform routine tasks.

You can upload the following types of SSH keys to a host using HTTPS PUT:

Authorized keys file for root user

DSA public key

RSA key

RSA public key

Do not modify the /etc/ssh/sshd_config file.
