Re: xdg-basedir for secrets

To me, secrets are fundamentally different from data (even confidential
data) because they serve as a mean to authenticate you or authorize your
utilisation of some services.


I guess the question is: should there be a dedicated folder for secrets
or should they just be in XDG_DATA_HOME and manage differently by the
applications (through your configuration) ?
