Laravel 5 Default Authentication Changes -

is there detailed article on how default authentication works in laravel 5?

i make changes...

1. allowing login username , or email.
2. setting email verification.

i have found things on laravel 4 not apply 5. list of files need altered helpful.

i think offical laravel 5 docs describe authentication well: http://laravel.com/docs/5.0/authentication

for "username and/or email" part @ answer on question: how allow application login user username or mobile number in laravel 5?

the second point isn't hard too.

1. add email_validation (or that) table database
2. create controller handles validation requests (something foo.bar/validate/{email_token}
3. on registration, send user email link controller
4. validate user, remove token email_validation table , allow user login.
