Hello, I haven't downloaded or used this plugin yet. This would be a great plugin for my work, but not all of our mediawiki members would want to use 2-factor authentication. Is this user preference based? If not, I would like to place a future request, if anyone wants something to work on with this, to have the extension preference based. Anyway, great plugin, I prefer 2fa myself and wish that more places would give the opportunity to use it!
