Send Password Protected Emails in Gmail

When you send a regular email to a person, the email not only shows up in notification previews but can also be opened by anyone having access to their device or account. In short, you’re relying on the other person’s device and account security for your email’s privacy.

So, while sending confidential or private data over email, it’s always better to count on some extra security measures. Below is how you can send encrypted, password-protected emails on Gmail. Besides, I’ve also mentioned some alternatives. Read on.

1. Using Confidential Mode

Gmail added the Confidential Mode back in 2018. When enabled, it locks email with an SMS passcode instead of the traditional password method.

The emails sent in this mode are hosted on Google’s server and cannot be forwarded, copied, printed, or downloaded. Furthermore, you can set an expiry date and time for the email.

To send SMS passcode-protected emails in Gmail using Confidential Mode:

  1. Open Gmail on your computer and log in with your Google account.
  2. Click on Compose, add the recipient and create the email as usual.
  3. Now, tap the Confidential Mode button at the bottom.Send Password Protected Emails in Gmail

  5. Send Password Protected Emails on GmailClick on Save. Then, tap Send.
  6. When prompted, enter the recipient’s mobile number and send the email.
  7. To access the email, the recipient will have to use OTP received on his phone via SMS.

How does this help? The recipient needs to verify their identity by completing the OTP verification. This ensures that only the authentic person has access to the email. However, as a limitation, this requires you to have their mobile number.

2. Password-Protect Gmail Attachments

The easiest way to password-protect the attachments in Gmail is to archive them into an encrypted ZIP or RAR file. To do so, install 7Zip on your computer. Then, follow the steps given below:

  1. Right-click the files you want to send in your email.
  2. Select 7Zip and tap Add to Archive.Password-protect Gmail Attachments
  3. In the 7Zip window, enter your desired password under Encryption.
  4. Set the encryption method to AES-256.
  5. Click on OK.

Once the archive file is ready, attach it to the email. To unarchive and open the file, the recipient requires the password you set for it. You can share the password with the right person over a phone call, text message, or inform them directly in person.

3. Alternative Way- Proton Mail

If you’re not restricted to using Gmail, try using ProtonMail. It is a popular email provider that lets you send emails secured with passwords.

By default, ProtonMail uses end-to-end encryption for emails. This means not even ProtonMail’s servers can decrypt or read your emails. In addition, you also get an option to send a password-protected email to anyone, regardless of which email provider they’re on.
