In addition to hashed / salted passwords, some are stored in plain text where no one else can read them.
For example ~/.netrc:
.netrcfile should be located in your home directory and the permissions on the file must be set so that you are the only user who can read it, i.e. it is unreadable to everyone else. It should be set to at least Read (400), or Read/Write (600).
For small developers who wish to avoid the complexities of managing passwords with hashing algorithms, the ~/.netrc methodology can be considered. The methodology is used in SSH to automatically log into remote servers.
