Your first alternative would make the password string available to all logged-in users via the "ps" command.

Your second alternative will still be stuck with line buffering -- even with $| set to non-zero everywhere on every file handle, the standard print function and diamond read operators will operate only in line-buffered mode ($| merely makes sure that consecutive lines are not buffered into chunks of 4KB or 8KB or whatever the pipeline buffer size happens to be).
