A user may wish to use 2 factor authentication and print out the sheet for safekeeping. As this may be a bit unwieldy for e.g. a wallet, it would be nice to offer the option for putting the 2 factor sheet onto a small business card, on two sides.
This can be all done in HTML easily, presented on the site, and a PDF downloaded for printing, or simply allowing printing directly from the site.
Recommend to move this project to sysadmin.
This is not an initiative that would be first tackled by the www team
closing, unclear what this refers to
This likely refers to the KDE Identity two factor system, which uses a card grid.
When it's replaced we'll move to a more modern TOTP / FIDO Hardware Token system, so not much to be done here.
