Yes, what people often call "authentication app" is a misnomer which
I resent (it's often accompanied with an application name or a link to
it, suggesting that the software (typically proprietary, of course) is
the one and only you can use).  It really (usually) means the
authentication uses the TOTP protocol, for which there are several Free
Software implementations readily available.

AFAIK the Somu (and presumably other Solokeys) does not require any
proprietary software.  I'd be happy to hear confirmation from someone
who actually dug into the matter, tho.
