The username is your unique identifier. An email works well for this because no one on the planet can have the same email account as me.
The password (in conjunction with your unique identifier) is what protects your account.
Thousands of people have access to my email address, but my password is complex enough that it would take a significant brute force hack to get in my account.
If Delta really wanted to be more secure, they'd allow for more complex passwords by opening up the special character set.
