+Authelia allows for a wide variety of time-based OTP settings. There are several applications which can support these
+algorithms and this matrix is a guide on applications that have been tested that work. It should not be assumed if an

+may now support some that were not previously supported, or in rare cases they may support less than they previously
+did.
