in thread best way to store login information for a perl script?
Nonetheless, keeping authentication/login data out of program code is generally a good idea. Deciding whether to store such info in a separate (private, rw-------) data file (as opposed to requiring manual entry on every run) is a question of weighing the tradeoff between convenience vs. risk.
If someone other than me can see the contents of a file after I've done chmod 600 on it, and can decide to do something malicious with that, it means someone with malicious intent has root access on my system. In that case, exposure of login info on a twitter account would be the least of my worries.
