Security isn’t just a product feature — it’s a mindset. Moss gives your team the tools to prevent fraud before it starts. Here’s how to activate your core defences.


1. Use Two-Factor Authentication (2FA)

Two-Factor Authentication (2FA) adds a second layer of security to your Moss account. It ensures that even if your password is compromised, your account remains protected.

Why 2FA matters:

  • Passwords are often reused across tools, which makes them easy targets

  • Fraudsters use stolen credentials from data breaches or phishing to break in

  • 2FA blocks over 99% of these automated login attempts

  • It’s mandatory for all Moss users.

Why the Moss Mobile App is more secure than SMS OTP:

  • SMS codes can be intercepted (via SIM swap or phishing)

  • The Moss Mobile App uses biometric login, encrypted token-based verification, and can’t be spoofed via fake links

  • In the Moss Mobile App we can provide you with additional information on your transactions, real-time alerts and advice on how to prevent fraud

Set up 2FA via the Moss Mobile App now:

  1. Go to your Moss profile > "Settings" > "Security"

  2. Follow the prompts to link your Mobile App

    (For full setup steps, see this guide or ask your CS Manager)


2. Secure Your Moss Account with the Mobile App

The Moss Mobile App is the most secure way to access your account and manage sensitive actions.

Why it’s safer:

  • No SMS codes to intercept or reuse

  • Built-in biometrics like Face ID or fingerprint authentication

  • Encrypted login flow verified directly in the app

  • Instant alerts for logins, approvals, or suspicious activity

What you can do with the Moss Mobile App:

  • Get real-time alerts for security events

  • Approve payments and expenses securely on the go

  • Block or freeze cards instantly if something feels off

3. Use Moss card controls & approval flows

Finance teams shouldn’t need to chase spenders — Moss gives you control from the start.

How to lock down spend:

  • Set per-user or per-card spending limits

  • Block or freeze cards instantly from the web or app

  • Enforce multi-level approvals for requests, payments, and reimbursements

Why it matters:

  • Prevents rogue spend or fraud from inside and outside the company

  • Gives visibility across teams, departments, and use cases

  • Audit-ready, with a full activity trail for every action
