Which action can help prevent unauthorized access to Google Workspace accounts?

Implementing two-factor authentication (2FA) is a critical action in preventing unauthorized access to Google Workspace accounts. This security measure enhances account safety by requiring users to provide two different forms of verification before gaining access. Typically, this involves something the user knows (like a password) and something the user has (such as a mobile device that receives a one-time code). Even if an attacker were to obtain the user's password, they would still need the second factor to bypass the security barrier, significantly reducing the risk of unauthorized access.

The other options do not provide adequate protection against unauthorized access. For example, encouraging password sharing undermines security by allowing multiple individuals access to the same account, which increases the likelihood of unauthorized access. Similarly, using easily remembered passwords can make accounts more vulnerable as they are often weaker and easier for attackers to guess or crack. Allowing device access without verification completely bypasses any security checks, making accounts highly susceptible to unauthorized access. Thus, implementing two-factor authentication stands out as the most effective and proactive measure to safeguard Google Workspace accounts.
