What is a necessary step for protecting user accounts in G Suite?

Enforcing two-factor authentication (2FA) is a crucial step in protecting user accounts in G Suite because it significantly enhances account security by adding an extra layer of verification beyond just a password. With 2FA enabled, even if a user's password is compromised, an attacker would still require a second form of authentication to gain access to the account. This can take the form of a code sent to a mobile device, a verification app, or other methods that ensure the person attempting to log in is indeed the account owner.

In today's security landscape, relying solely on passwords is insufficient due to the prevalence of phishing attacks and data breaches. Implementing 2FA helps mitigate these risks and boosts overall account security, making it a necessary component for safeguarding user accounts. It's especially important in environments where sensitive data may be handled or where compliance with regulations like GDPR or HIPAA is necessary.
