Hi Tri, have you found the answer to your question?

Hi,

In Odoo addons, there is a module named 'auth_signup'. In that module, it has a controller main.py code you can see the method.

@http.route('/web/signup', type='http', auth='public', website=True, sitemap=False)
  def web_auth_signup(self, *args, **kw):

Where you can get all ready made user authorisation including email validation for the users logging in from odoo website.

Hope it helps
