The module uses the Python email_validator library to perform a strict two-level check. First, it checks the syntax (e.g., ensuring the @ and domain extensions are present). Second, it checks the domain's deliverability (ensuring the email domain actually exists). If a user enters a fake email (like test@fake-domain-xyz.com), the system stops the signup and displays the error: "That does not seem to be an email address.

In this module, the "Password" and "Confirm Password" fields are removed from the signup page. The user only needs to provide their Name and Email. The system creates the account in the background but does not allow immediate login. Instead, it sends an activation link to the provided email. The main benefit is that it prevents fake accounts and bots, ensuring that every registered user has a valid, verified email address.

The system automatically checks the Odoo database (res.users model) for existing records. If a user tries to sign up with an email that is already registered, the system catches the duplication and prevents a crash. Instead, it shows a user-friendly error message on the screen: "Another user is already registered using this email address.

Once the user clicks the "Sign up" button with a valid email, Odoo creates the user account in the background and immediately triggers a "Reset Password" email via the outgoing SMTP server. The user sees a success message: "Check your email to activate your account!" They then open their personal inbox, click the secure link provided in the email, set their preferred password, and gain access to the system.
