I have Ubuntu 22.04.4 LTS distro on my WSL2 (hosted on my Windows 11 23H2 x64 Pro).
And I need to securely and persisently store credentials in non-interactive manner (without any user prompt).
Secret Service API definitelly require GUI, Git credential cache is not persistent, Plaintext files are not secure at all.
I've tried to use GPG/pass compatible files store. But if I set a passphrase for a generated GPG key a prompt starts to open in WSL2 terminal window (or in a GUI window if Seahorse is installed):

So GPG/pass compatible files don't require any interaction only if GPG key has no passphrase? No other options available on Linux?
