Yes, it is possible to establish an SSH connection using an SSH certificate. SSH certificates are a form of authentication that can be used to access remote servers without requiring a password. When a user presents an SSH certificate to a remote server, the server uses the public key contained within the certificate to verify the user’s identity and grant access to the system. This process is highly secure and eliminates the need for users to remember or store passwords, making SSH certificate authentication an excellent option for secure remote access.
