I may have done this at an employer. You don't need a keyboard with programmable macros, though, just a way in the OS to setup a keyboard shortcut to run a command. In Linux it's super easy to make "super + x", or other modifiers + key, execute a bash program. That bash program can then use xdotools to type a password, generated and type a 2FA token, type a ¯\_(ツ)_/¯ string (because slack imagified the emoji version making it unreadable), whatever...
