In this guide, you will learn how to protect your data and the answer to the question: how secure is Google Sheets?

How Secure Is Google Sheets?

Google Sheets is pretty safe to use. All files saved in the cloud are encrypted with 128-bit encryption, so no one else can see or change them without your permission. Also, every change made to a document is recorded, so you can see exactly what was changed and by whom.

Digital security is important for individuals and businesses alike, yet it’s often hard to tell how secure the services we rely on actually are.

With the increasingly common news articles about data breaches and other security threats, it’s important to take the time to look at the tools you and your company use and ensure that they’re safe.

Is Google Sheets Safe? (Quick answer)

  • Google Sheets is protected by end-to-end encryption and regular third-party audits.
  • A large number of security breaches are due to user error, so it is important to use strong passwords, not reuse passwords, and enable two-factor authentication.
  • Be wary of clicking on links in emails, as they may be phishing attacks.
  • Google Sheets may not be as secure as other platforms.
  • It is difficult to ensure that all users are following best practices for data security.

Google Sheets Security Overview

If you’ve read about past security issues like storing unhashed passwords, you may be concerned with entrusting your data to the system.

But Google works hard to protect your data and rapidly fix any security issues that are uncovered with cutting-edge technology.

While Google’s end-to-end encryption and other security features are sound, you should keep in mind that a large percentage of security breaches are due to human error. More information on how to protect yourself is included in the next section

Below is a list of some of the ways Google protects Google Sheets and other Google Drive files:

  • End-to-end encryption of all data
  • Regular audits conducted by third-parties to ensure truthfulness of Google’s claims
  • Google also offers cash rewards up to tens of thousands of US dollars to anyone who can find security vulnerabilities in Google’s services

How to Protect Your Data (4 Best Practices Tips)

A large number of security breaches aren’t due to faulty encryption or poor data storage practices, but instead come from user error.

Despite how secure Google’s servers and data transfer protocols are, the question of how secure Google Sheets is really comes down to how well users understand security.

Think of it this way:

It doesn’t matter how secure your locks are if you hand a burglar the key to your home.

The following is a list of best practices to help ensure that data stored in Google Sheets is secure

1. Use strong passwords

Ensure your passwords are strong.

A weak password can be cracked in fractions of a second regardless of how carefully you protected it.

But a 12-character password with upper and lowercase characters, numbers, and special characters would take thousands of years to crack with today’s technology

2. Don’t reuse passwords

Don’t reuse passwords and update them regularly.

Password managers can help make this easier

3. Use 2-factor authentication

Use 2-factor authentication for all accounts that store sensitive information.

If you are sharing Google Sheets with sensitive information, consider requiring others with access to the sensitive information to also enable 2-factor authentication

4. Only click safe links

Don’t click on links in email unless you’re certain they’re safe.

One example of a dangerous link is a common phishing attack that recreates the look of a login page such as Google’s, then steals your login info when you attempt to login

If you follow the above practices carefully, Google Sheets is a secure option for storing sensitive information.
