TL;DR: If someone guesses or steals your password, two-factor authentication (2FA) is the only thing standing between them and your business. This guide walks you through enabling 2FA on every critical business platform -- using authenticator apps, not SMS -- in priority order. Start with email, then payment, then ad accounts, then everything else.

Here is a scenario that happens more often than you think: someone gets your email password from a data breach. They log in, reset your Stripe password, transfer your funds, then lock you out of your own Meta Business Manager. By the time you notice, your ad account is running ads for someone else and your payment processor is compromised.

Two-factor authentication stops this entire chain at step one. Even if they have your password, they cannot log in without the second factor -- a time-sensitive code from your phone.

This takes 5 minutes per account. The cost of not doing it is your entire business.

Do not use SMS text messages for 2FA. Here is why:

Use an authenticator app instead:

Authenticator apps generate codes locally on your device. No network required. No interception possible.

Not all accounts are equally critical. Here is the order:

This varies by registrar but follows the same pattern:

Also enable registrar lock on your domain. This prevents unauthorized domain transfers even if someone accesses your account.

Additional Stripe security:

Important: Meta requires 2FA at the personal Facebook account level, not just the Business Manager level. Both must be enabled.

Repeat for any other automation tools (Make/Integromat, ActiveCampaign, ConvertKit, etc.).

Every platform gives you backup codes when you enable 2FA. These are one-time-use codes for when you cannot access your authenticator app (lost phone, broken device).

How to store backup codes safely:

Prevention: If you use Authy, enable multi-device sync so your codes are available on a second device (tablet, backup phone).

Add this to your monthly routine:

Two-factor authentication (2FA) requires two forms of identification to log in: something you know (your password) and something you have (a code from your authenticator app). Even if someone steals your password, they cannot access your account without the second factor.

SMS codes can be intercepted through SIM swapping attacks, where an attacker convinces your phone carrier to transfer your number to their device. Authenticator apps generate codes locally on your device, making them immune to this attack.

Google Authenticator or Microsoft Authenticator are both free and reliable. If you already use 1Password as your password manager, its built-in authenticator is convenient. Authy offers multi-device sync if you want backup access from a second device.

Contact each platform's support team with proof of identity and business ownership. This process can take days to weeks depending on the platform. This is why storing backup codes securely is critical.

Yes. In Meta Business Manager, you can require 2FA for all team members in Security Center settings. For other platforms, make it a policy requirement for anyone with account access.
