Add an SSH key for an admin user

You can use secure shell (SSH) public keys to log into the SSH console without typing a password. You must add SSH public keys to the user account to configure SSH password-less authentication.

Procedure

In the top navigation bar, select
The administration page opens.
In the Settings section, select Users.
The Users management page opens.
In the top right section, select Users.
The Users page opens.
To the left of the applicable user, select the icon.
A dialog shows.
In the field, paste the public key in the SSH public keys for web user admin field.

Note:
Every admin user has a key. If you need more than one key, paste one per line. Non-admin users must use a password for secure shell (SSH) authentication. When an admin user leaves, the associated SSH keys are removed.

Note:
The pasted key should not contain new lines. The system will not use invalid keys.
Optional: To enable logging in with the root account, select Allow root login using SSH keys.
Select Edit ssh keys.

Results

The SSH public keys are propagated to all the sensors that are directly connected. The default key propagation interval is 30 minutes. You can change this with:

conf.user configure
                ssh_key_update interval <seconds>

in the CLI.
