What's the correct use of \author when multiple authors?

The \maketitle command with \author allows a simple separation of two (or more) authors by using the \and command. See code below for some inspiration.

\documentclass[11pt,english]{article}
\usepackage[T1]{fontenc}
\usepackage{babel}

\author{
  LastName1, FirstName1\\
  \texttt{[email protected]}
  \and
  LastName2, FirstName2\\
  \texttt{[email protected]}
}
\title{Usage of the \texttt{\textbackslash author} command}

\begin{document}
  \maketitle
\end{document}
