How lock particular mail in gmail with password

Unfortunately, Gmail does not have a built-in feature to lock a specific email with a password. However, there are a few workarounds to achieve a similar effect:

Method 1: Use Gmail's built-in encryption

You can use Gmail's built-in encryption feature to encrypt a specific email. This will require the recipient to have a decryption key to access the email. Here's how:

  1. Compose a new email or open an existing one.
  2. Click on the three vertical dots at the bottom of the compose window.
  3. Select "Encrypt" from the dropdown menu.
  4. Enter the recipient's email address and a decryption key (a password or a phrase).
  5. Click "Encrypt" to encrypt the email.

The recipient will need to have the decryption key to access the email. Note that this method is not foolproof, as the decryption key can be shared or compromised.

Method 2: Use a third-party email encryption service

There are several third-party services that offer email encryption, such as ProtonMail, Tutanota, or Mailvelope. These services allow you to encrypt specific emails with a password or a phrase. Here's how:

  1. Compose a new email or open an existing one.
  2. Use the third-party service's browser extension or plugin to encrypt the email.
  3. Enter the recipient's email address and a password or phrase to encrypt the email.
  4. Send the encrypted email to the recipient.

The recipient will need to have the decryption key to access the email. Note that these services may have limitations or requirements for usage.

Method 3: Use a password-protected attachment

Another approach is to attach a password-protected file to the email. This will require the recipient to have the password to access the attachment. Here's how:

  1. Compose a new email or open an existing one.
  2. Attach a file to the email.
  3. Use a password-protecting tool, such as 7-Zip or WinZip, to encrypt the attachment.
  4. Send the email to the recipient.

The recipient will need to have the password to access the attachment. Note that this method is not foolproof, as the password can be shared or compromised.

In summary, while Gmail does not have a built-in feature to lock a specific email with a password, there are workarounds using Gmail's built-in encryption, third-party email encryption services, or password-protected attachments.
