Log in to your hosting with an SSH key

This guide explains how to log in to a hosting using a SSH key.

Requirements

1. Create an FTP + SSH account via the Manager (help)
2. Create an SSH key with a secure algorithm, for example ed25519:

ssh-keygen -t ed25519

, because with an rsa key ("ssh-keygen" or "ssh-keygen -t rsa"), login will be refused and the following error will be returned in verbose mode:

debug1: send_pubkey_test: no mutual signature algorithm

Deposit the SSH key

1. log in to the SSH server of your hosting (help)
2. go to the root of your hosting: cd ~
3. create the “.ssh” directory: mkdir .ssh
4. modify the rights to the “ssh” directory to chmod 700
5. create the authorized_keys file and paste your SSH key on a single line (important)
6. modify the rights to the authorized_keys file to chmod 600
