Best Practices for Cybersecurity with Google Authentication

Two-factor authentication is the single most effective step you can take to protect your Google Workspace account. It requires not only your password but a second form of verification — typically a code sent to your phone, a hardware key, or a Google prompt — before granting access.

Even if an attacker obtains your password through phishing or a data breach, 2FA stops them cold. Google reports that adding a phone-based second factor blocks 100% of automated bot attacks and the vast majority of targeted phishing attempts.

For Google Workspace admins, go further:

• Enforce 2FA org-wide from the Admin Console — don't leave it optional
• Consider requiring physical security keys (e.g. Titan Key) for high-privilege accounts
• Set an enrollment period and monitor compliance from the Security dashboard
• Enable Advanced Protection for executives and anyone with access to sensitive data

Every time a user grants a third-party app access to their Google account, that app becomes a potential entry point into your organization's data. Over time, employees accumulate dozens of connected apps — many of which are forgotten, unused, or no longer maintained by their developers.

Periodically auditing and removing unnecessary OAuth grants is a critical hygiene task that most businesses overlook. A compromised third-party app can silently exfiltrate email, calendar data, and Drive files.

Recommended audit steps for admins:

• In the Admin Console, navigate to Security → API controls → App access control
• Review all apps with access to Google data — flag any you don't recognize
• Block or restrict apps that aren't business-justified
• Enable domain-wide app allowlisting to prevent unauthorized OAuth grants
• Schedule this audit at minimum once per quarter

Outdated software is one of the most common and avoidable attack vectors in any organization. Every application connected to your Google Workspace environment — browsers, desktop sync clients, third-party integrations, Chrome extensions — should be running its latest version.

Software vendors regularly release security patches to fix known vulnerabilities. Delaying those updates leaves your organization exposed to exploits that are already publicly documented.

Update hygiene checklist:

• Enable automatic updates for Chrome and Chrome OS across your fleet
• Keep the Google Drive desktop sync client current on all employee devices
• Use Chrome Enterprise to enforce browser policy and update schedules
• Audit Chrome extensions — remove any that are unverified or rarely used
• Patch operating systems on a regular schedule (don't wait for incidents)

Reusing passwords across services is one of the fastest ways to get compromised. When any service your employees use suffers a data breach, attackers immediately test those leaked credentials against Google, Microsoft, and every other platform — a technique called credential stuffing.

Every Google Workspace account should have a password that is unique to Google and strong enough to resist brute-force attacks.

Password requirements to enforce:

• Minimum 14 characters — longer is always better
• Mix of uppercase, lowercase, numbers, and symbols
• Never reused from another service
• Changed immediately if a breach is suspected

For most organizations, the best solution is a business password manager that generates and stores unique credentials for every service. Combined with 2FA, strong unique passwords make credential-based attacks effectively impossible.

Google Workspace admins can also enforce minimum password length and strength requirements org-wide from the Admin Console under Security → Password management.
