Hello, this is a feature request.
Back when I was still using GnuPG to store my keys there was this feature where you could make it remember the passphrase for a given amount of time since its last usage. But after a while of inactivity, the backend would forget the cached passphrase and the user would have to re-enter the key password in order to be able to use PGP again.
I was hoping something like this could be added to Nitrokey 3. Currently the device is unlocked on its first use, but then it stays unlocked for the duration. As a potential security enhancement, the key could be programmed to lock itself after a while of inactivity. Perhaps this could be configured via the admin interface like pynitrokey (or was it nitropy?). Add an option to enable/disable it and an option where timeout is specified e.g. in seconds. This shall apply to the smartcard (OpenPGP) key storage, but may potentially apply to other parts that are unlocked only once.
Thanks.
