Apply two-factor authentication throttling

This guide explains rate controls protecting repeated 2FA-code submissions.

What this guide helps you do

Understand rate controls protecting repeated 2FA-code submissions. 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

• 2FA verification attempts

Rules and limits

• Repeated invalid 2FA codes are constrained.
• Use the authorised recovery process after a legitimate lockout.
• Do not widen CSRF exclusions or weaken the first authentication factor.

Check 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.
