Why use "username" as identity field and not the "id"?

[rafis]

Why you use "username" as identity field, while most auth engines I have encountered in PHP uses used_id as identity?

[kennethklee]

by default, this module uses id as the primary key. see

passport-local-sequelize/lib/passport-local-sequelize.js

Lines 35 to 39 in 3871eaa

	id: {
	type: Sequelize.INTEGER,
	autoIncrement: true,
	primaryKey: true
	},

username is just a normal field. if PHP uses id as a username, it's very very incorrect. i have enough trouble remembering my ICQ number.
