[Feature Request] Secure credential handling for multi-machine file sharing without exposing secrets in logs

Bug Description
this is a personal tool to connect across my machines not ssh to share files over thunderbolt and lan in aggregation, often use it to let my agents to reach to another machine without providing them with ssh or a key. earlier looked into concealing password from the logs that stay in console so that agents don't see it even when i type it to allow a sudo operation and the entire project got flagged.
