Public-key authentication <\/h2>\n\n\n\n

Due that at this point in our LAMP journey we are still working on a LAB, we’re not going to pay much attention to security measures, authentication via username\/password<\/strong> is good enough for a LAB environment, but you must know that there is a more secure option, and in fact this option is nowadays the standard when connecting to VPS<\/strong> (Virtual Private Server), we are talking about the “Public-Key Authentication<\/strong>” method, where we make use of a pair of SSH keys Public\/Private, this particular subject is covered in this article<\/a>. <\/p>\n\n\n\n

Immediately after the creation of a new folder you may want to create a new session, the wizard will guide you and you’ll be able to choose the connection protocol, telnet<\/a>, SSH<\/a>, etc, and also to enter the user credentials, in this example we’re going to authenticate ourselves using a the pair username\/password.<\/p>\n\n\n\n
