This article does not mention that environment variables are also visible by process in /proc/*/environ (which has restrictive permissions, but is completely visible to root).
PuTTY has added a -pwfile option for use in ssh. If not exported, this interface is likely the best for non-key batch use. It seems much superior to sshpass.
The old .netrc format can be adapted for storage (which appears popular for curl), but I prefer sqlite databases, with permissions removed for all but the owner.
