SSH keys str vital pairs determined by community important infrastructure (PKI) engineering, They can be useful for electronic id authentication and encryption, to provide a protected and scalable approach to authentication.

Within the file, hunt for a directive known as PasswordAuthentication. This can be commented out. Uncomment the line by eradicating any # at the beginning of the line, and set the worth to no. This could disable your capacity to log in by means of SSH working with account passwords:
