Actually to be honest, if I could login to Mediawiki with a public/private keypair I would actually really enjoy that. Certainly it shouldn't be the default, but in a very non-joking way, I would support an initiative to add that as an option.
You mean kind of like this? https://www.mediawiki.org/wiki/Extension:SSLClientAuthentication
Pretty close. I was actually thinking well known PGP keypair, but SSL cert signed by a trusted CA works just as well. I'll fool around with that extension later today. Thank you!
Thank you, Derric Atzrott
