BibTeX entry

 @misc{ wiki:xxx,
   author = "icesus",
   title = "Captcha --- icesus{,} ",
   year = "2020",
   url = "https://naga.icesus.org/wiki/index.php?title=Captcha&oldid=4466",
   note = "[Online; accessed 23-October-2025]"
 }

When using the LaTeX package url (\usepackage{url} somewhere in the preamble) which tends to give much more nicely formatted web addresses, the following may be preferred:

 @misc{ wiki:xxx,
   author = "icesus",
   title = "Captcha --- icesus{,} ",
   year = "2020",
   url = "\url{https://naga.icesus.org/wiki/index.php?title=Captcha&oldid=4466}",
   note = "[Online; accessed 23-October-2025]"
 }
