It must be a valid path.
You are writing your credentials in the terminal, and they probably will be stored in some logs as plain text.
Bash will store every executed command in ~/.bash_history and also the history that is kept in memory. You should clear that.
Right now, this is the only way to input your credentials, so deal with it or don't use it.
