The cloud VPS control panel has a very convenient ability to add automatically the user's public key to the installed VPS servers. After installing the operating system, the SSH key will be added to the root user in the file ~/.ssh/authorized_keys. This will allow you to connect via SSH to the Linux server console transparently, without entering a password.
The configuration should be done in the cloud VPS Control Panel https://onevdc.net
1. Go to the Setting Section of the user profile
2. Select the Config tab and press the "Add SSH Key" button
- This public key will be automatically connected to all servers installed in the future. The servers installed earlier, before registering the SSH key, will not be affected by the procedure.
If you want to connect public keys to existing VPS servers, please, see the articles in the knowledge base
