module Doorkeeper::Orm::ActiveRecord::Mixins::AccessGrant

returning a present value for persisted tokens.
while hashing strategies do not, so you cannot rely on this value
Some strategies allow restoring stored secrets (e.g. symmetric encryption)

The stored refresh_token may be mapped and not available in cleartext.
We keep a volatile copy of the raw token for initial communication
