Footnote with a numbering style in \author

Question

In LaTeX, I want to define the footnote numbering as a), b), c),... at the superscript of an author inside the \author{} command. If I use \thanks inside \author{}, the footnote numbering is different than a), b), c),... and I am unable to modify the numbering style of \thanks command.

Please see the code below and suggest an edit. Thank you.

\documentclass{article}
\begin{document}
    \title{Numbering footnote in author sample code}
    \author{AA \thanks{[email protected]} \\
        BB \thanks{[email protected]}}
    \maketitle
\end{document}

Answer 1

The footnote numbering of \thanks is set to \@fnsymbol, so you can probably replace it with \@alph to change it to alphabetical 'numbering'.

\documentclass{article}
\makeatletter
\renewcommand*{\@fnsymbol}[1]{\@alph{#1})}
\makeatother
\begin{document}
    \title{Numbering footnote in author sample code}
    \author{AA \thanks{[email protected]} \\
        BB \thanks{[email protected]}}
    \maketitle
\end{document}
