There's a number of offline, opensource, TOTP CLI applications, so just use one of them for instance?

Those can be used? That could be a way around this then, thanks -- I'll investigate (just going on @badsectoracula's comment that phone or key is required, possibly I misinterpreted that).

Still something of a PITA though (and not really a second factor).

KeepassXC is great. Just keep a copy of your .kbdx file synced to a backup location.
