How to Password Protect a Google Doc
Want to add a password to your Google Doc? While Google Docs does not have a built-in password feature, there are several ways to secure your documents. This guide covers sharing restrictions, Gmail Confidential Mode, PDF encryption, and third-party options for protecting sensitive Google Docs.
Quick Answer
Google Docs does not have native password protection. The best alternative is to use restricted sharing: Click Share > Change "Anyone with the link" to "Restricted" > Add specific people by email. Only those Google accounts can access the document.
Need a true password? Download as PDF and encrypt it, or use Gmail Confidential Mode to require an SMS passcode.
Google Docs Security Options
Before diving into specific methods, understand what Google Docs offers natively:
| Feature | What It Does | Password? |
|---|---|---|
| Restricted Sharing | Limits access to specific Google accounts | No (uses Google login) |
| Gmail Confidential Mode | Sends link with SMS passcode requirement | Yes (SMS code) |
| Download Restrictions | Prevents viewers from downloading/printing | No |
| Link Expiration | Sets document to expire after a date | No (Workspace only) |
Important: There is no way to add a traditional password dialog to a Google Doc that opens before viewing. The methods below provide password-like security through different mechanisms.
Method 2: Gmail Confidential Mode (SMS Passcode)
Gmail Confidential Mode provides the closest thing to password protection. Recipients must enter an SMS passcode sent to their phone to view the content.
How to Use Confidential Mode
- Open Gmail and compose a new email.
- Click the lock with clock icon at the bottom of the compose window (Confidential mode).
- Set an expiration date for when the content becomes inaccessible.
- Under "Require passcode", select SMS passcode.
- Click Save.
- Attach your Google Doc or include a link to it in the email.
- Enter the recipient's email address and phone number (for SMS).
- Send the email.
What Recipients Experience
- They receive an email stating content is protected.
- They click to view and are prompted for a passcode.
- Google sends an SMS code to their phone.
- They enter the code to access the content.
| Feature | Confidential Mode |
|---|---|
| SMS Passcode | Yes, sent to recipient's phone |
| Expiration Date | Yes, 1 day to 5 years |
| Prevent Forwarding | Yes |
| Prevent Copy/Download | Yes (no copy, download, print) |
| Revoke Access Anytime | Yes |
Limitation: Confidential Mode protects the email content, not the Google Doc itself. If you share a link to a Google Doc, the doc still follows its own sharing settings. For best protection, attach the doc as a PDF or copy content directly into the email.
Method 3: Download as PDF and Encrypt
For true password protection, download your Google Doc as a PDF and add a password using encryption tools. The recipient will need the password to open the file.
Step 1: Download as PDF
- Open your Google Doc.
- Go to File > Download > PDF Document (.pdf).
- Save the PDF to your computer.
Step 2: Add Password Protection
Use one of these tools to encrypt the PDF:
Adobe Acrobat
PaidProfessional tool with full encryption options. Open PDF > Tools > Protect > Encrypt with Password.
SmallPDF
FreeFree online tool. Upload PDF, set password, download encrypted file. smallpdf.com/protect-pdf
PDF24
FreeFree online and desktop tool. Upload, add password, download. pdf24.org/en/protect-pdf
Preview (Mac)
FreeBuilt into macOS. Open PDF > File > Export > Enable "Encrypt" checkbox and set password.
Step 3: Share the Encrypted PDF
Send the password-protected PDF via email, file sharing, or any method you prefer. Share the password separately (via phone call, text, or different email) for best security.
Method 4: Third-Party Security Tools
Several third-party tools integrate with Google Drive to add password protection:
Boxcryptor (now part of Dropbox)
Desktop AppEncrypts files in Google Drive with your own encryption key. Files are encrypted before uploading.
Cryptomator
Desktop AppOpen-source, free encryption tool. Creates an encrypted vault in your Google Drive where you store sensitive documents.
GAT+ for Google Workspace
Admin ToolEnterprise tool for Google Workspace admins. Adds DLP (Data Loss Prevention) and access controls.
Virtru
Chrome ExtensionEmail and file encryption for Google Workspace. Adds password protection to emails and attachments.
For most users: Restricted sharing combined with Google's built-in security is sufficient. Third-party tools are mainly for organizations with strict compliance requirements.
Tips & Best Practices
Restricted sharing is often enough
Google accounts with two-factor authentication provide strong security. For most documents, restricted sharing is sufficient protection.
Never share passwords in the same email
If you send a password-protected PDF, share the password through a different channel (phone, text, separate email) to prevent interception.
Audit your sharing settings regularly
Check who has access to your important documents periodically. Remove access for people who no longer need it.
Use version history for accountability
Google Docs keeps a complete version history. This helps track who made changes and when, adding another layer of security.
Consider Google Workspace for business
Google Workspace offers additional security features like link expiration, audit logs, and admin controls not available in free accounts.
Disable download for viewers
In sharing settings, uncheck "Viewers can download" to prevent people from making copies. Note that determined users may still screenshot.
