Public key authentication is an authentication method that lets you log in securely without a password. This method uses a private and a public key to authenticate users. The public key must be stored in the project if you wish to configure key-based authentication. The private key is saved locally on your computer and can also be assigned a password for added security. You can set a public key for a user as follows:
Select the desired project.
On the Website tab, click subtab SFTP & SSH.
Click the three vertical dots next to the SFTP/SSH user you want to configure.
Click Set public key.
Paste the public key in the box.
Click Save changes.
The public key is now set.
