It would be useful to be as inclusive as possible in this plugin description.
By indicating only that it works "with Google Authenticator" this may give the impression it only works with GA.
Other applications that this may work with, as I understand it, are KeepassXC, AndOTP, etc.
I would propose "Plugin to add two factor authentication (2FA) support to sysPass login for applications that implement Time-based One-time Password Algorithm (TOTP) as specified in RFC 6238.
This has been tested with AndOTP, KeepassXC, Google Authenticator."
