Understand Argon2id password hashing

This guide explains the one-way password algorithm applied to newly created or changed credentials. The guide then takes you through the correct route, the checks to complete before making changes, the workflow in order, and the evidence to review afterwards.

What you’ll accomplish

Understand the one-way password algorithm applied to newly created or changed credentials. The workflow below follows the supported application or module flow and does not invent a menu or bypass validation.

Follow these steps

1. Use the supported Britixo CRM release or workflow that produces this security control.
2. Check the expected protection through an authorised test.
3. Record the result in the deployment or security audit evidence.

Fields and options to review

• Password entered through the normal staff/client workflow

Rules the system enforces

• New or changed passwords are stored with Argon2id.
• Passwords remain one-way and must be verified through the application authentication service.
• Plaintext or reversible password storage is not supported.

How to confirm it worked

• The protection is active without weakening another security control.

Security, audit and troubleshooting checks

• Use the exact authorised account, role and record before saving or sending.
• Verify the saved status and downstream record; a browser success message alone is not sufficient evidence.
• Never expose passwords, API keys, access tokens, protected attachments or raw server paths in support tickets.
• Do not edit module or core database records directly to bypass validation, permissions, migrations or state rules.
