Multi-factor authentication (MFA)

Stronger logins. Safer systems. Less risk.

A password alone is not enough. Phishing attacks, data breaches, and password reuse make traditional login methods too easy to exploit.

Multi-Factor Authentication (MFA) adds an extra layer of protection by requiring users to verify their identity with something more than just a password.

LeftBrain helps you choose, implement, and manage MFA that fits your systems, team and tolerance for risk.


What is Multi-Factor Authentication?

MFA requires two or more verification steps to confirm a user’s identity before granting access.

These steps fall into categories:

  • Something you know (like a password)
  • Something you have (like a phone or security key)
  • Something you are (like fingerprint or face recognition)

Used properly, MFA prevents unauthorised access even if a password is stolen or guessed.


Why MFA matters

Without MFA, one stolen password can compromise your entire organisation.

Enabling MFA reduces the success of phishing attacks and account takeovers.

It is also a key requirement for most security certifications.

Here are the real-world risks of skipping it:

  • Business email compromise
  • Unauthorised access to client or financial data
  • Failing security audits or tenders
  • Higher insurance premiums and regulatory exposure

MFA does not eliminate every threat, but it significantly reduces the most common and dangerous ones.


Not all MFA is created equal

Many businesses enable basic MFA and assume they are protected. But the type of MFA you use makes a difference.

We help you understand the options:

  • Text message MFA is the weakest, vulnerable to interception or SIM swapping
  • Authenticator apps (like Microsoft or Google Authenticator) are more secure and widely supported
  • Push notifications with approval prompts offer user-friendly protection
  • Number matching and device proximity reduce phishing risk
  • Hardware security keys (such as YubiKey) offer the highest level of protection

We help you balance security, usability and cost to find the best fit for your team.


Our process

LeftBrain takes a practical, business-first approach to MFA deployment.

Step 1: Audit your current access setup

We start by reviewing:

  • Whether MFA is in place
  • Which methods are used, and by whom
  • What tools or licences you already have available
  • Where you are most vulnerable

We often discover that secure tools are already available, just not configured or enforced.

Step 2: Define your MFA policy

We help you decide:

  • Which teams and roles need which level of protection
  • How to implement security without disrupting daily work
  • What recovery steps to put in place if access is lost
  • How to communicate the change to your team

This ensures you get the right level of protection without creating unnecessary friction.

Step 3: Implement across your systems

We deploy MFA in:

  • Google Workspace and Microsoft 365
  • Dropbox, Zoom, Slack, Notion and similar apps
  • Admin tools, control panels and cloud infrastructure
  • Password managers and mobile device access

We handle setup, documentation and user onboarding, making the rollout smooth and manageable.


Compliance and certification

MFA is a requirement for:

We help you:

  • Implement MFA in line with best practice
  • Document access controls and enforcement
  • Demonstrate compliance to auditors and clients

Whether you are preparing for certification or just want to reduce risk, MFA is a foundational step.
