Portal user
> Portal user is a user who is generally external to the organization such as customers/clients. We can give Odoo portal access to those users so that they will get access to information that is related to them.
> A portal user has only read/view access, they will not be able to edit any document in the system. A portal defines a specific user menu and access rights for its members. This menu can be seen by portal members, public users and any other user that have access to technical features (e.g. the administrator). Also, each portal member is linked to a specific partner.
How to enable portal access?

By activating the customer portal, when you send a document to a customer (quotation, invoice), your customer will be able to signup to get all his documents, read the company news, check his projects, etc.
