FTDv cli password recovery

[Dkiptoo]

Hi, I have FTDv managed by FMCv both residing on the same VMWare EXSi host. I want to recover the cli password of the ftd. Any leads will be highly appreciated

If you setup external authentication in FMC and enable it for ssh access on the devices, you can use an admin level login with RADIUS-based authentication. With that, you can login to the FTDv and change the local admin password.

Otherwise, there is no direct recovery method by design.

How can I achieve this given that we don't have RADIUS  server such as  ISE? Can Windows Server NPS achieve this? If so,  any leads to documentation walkthrough?.  Also, I accessed the console on ESXi and interrupted the boot process where I was presented with the following screenshot. Not sure what do next if I ware to rest  password through this methodology. First option would be great if I can get any leads as it carries less risk.
