Hope This Helps

Vault ist ein Passwort Manager und mehr für den professionellen Einsatz. Die Sicherheitsfeatures sind beeindruckend und das alles in einem OpenSource Tool das keinen Cent kostet. Unter anderem bietet das Tool die Möglichkeit OneTimePasswords (otp) zu erstellen. Unter Linux sind die otp einfach zu nutzen unter Windows leider nicht ganz so einfach.

Um eine ähnlich komfortabele Lösung für Windows Benutzer zu bieten habe ich hier ein kleines Powershell Skript geschrieben.
Es wird putty vorausgesetzt anderenfalls umschreiben

Hier gehts zu Vault von Hashicorp : https://www.vaultproject.io/

Eine Anmeldung mit einem Token sieht dann so aus :

Eine Anmeldung mit user/pass ist auch möglich:
