Employee PIN Generator

.. contents:: :local: :depth: 1

Overview

This Odoo 19 module automatically assigns a unique, randomly generated 6-digit PIN to every employee record. The PIN is enforced to be globally unique across all companies in the same Odoo database via a SQL UNIQUE constraint.

Features

• Auto-generates a 6-digit numeric PIN when a new employee is created.
• PIN uniqueness is enforced at the database level (UNIQUE constraint on employee_pin).
• No two employees — even in different companies — can share the same PIN.
• A Regenerate PIN button is available on the employee form (Private Information tab) for HR managers and users.
• A confirmation wizard is shown before replacing the current PIN, displaying the existing value.

Technical Details

• Model extended: hr.employee
• New field: employee_pin (Char, size 6, unique)
• New transient model: hr.employee.regenerate.pin.wizard
• PIN generation retries up to 1,000 times to avoid collision in a crowded pool.

Installation

1. Copy hr_employee_pin into your custom addons path.
2. Update the addons list in Odoo (Settings → Activate Developer Mode → Update App List).
3. Install Employee PIN Generator from the Apps menu.
4. Existing employees will NOT receive a PIN automatically — use the Regenerate PIN button on each record, or run a one-time migration script.

Usage

When creating a new employee the PIN is generated automatically and shown in the Private Information tab under the Employee PIN section.

To regenerate the PIN:

1. Open an employee record.
2. Go to the Private Information tab.
3. Find the Employee PIN section and click Regenerate PIN.
4. Confirm in the dialog.
5. A success notification will show the new PIN.
