O autenticador gera códigos de verificação em dois fatores no seu navegador.
Clone of the Authenticator App, but includes prefix support while copying the OTP code. This was build mainly for personal use but then published :)
We were using sophos VPN which when MFA enabled ask for a password in the format ( passwordOPT ) which is VPN passwword has to be concatenated with the OTP. A bit weird but it was the only option. This upgrade helps us, and we can have prefix as the vpn password.
