Zyxel Firewalls - Urgent need of other 2FA methods! via Authentificator apps / Yubikey..?
are there any news according to 2FA with solutions like Microsoft Authentificator, Google Authentificator or Yubikey?
There are a lot of security concerns when having the only option as 2FA per mail. I am managing and integrating a lot of firewalls, where such a solution is not acceptable - no outgoing communications are allowed to mail server or there are situation, where the firewall is completely offline.
The worst case scenario is, when 2FA via email is activated and realized via online communication and the internet connection/WAN is down. There is no way to receive the code in such case.
Most of other brands are supporting other types of 2FA, especially solutions like Google/MS Authentificators - working offline with hashes...
Would it be possible to integrate these securtiy features?
Thank you very much for your support and reply.
PS: I had to post this topic here due to no answer under the section "IDEAS". I am sorry for that.
