Using a Master Password to Encrypt your Account Passwords


To streamline checking for new messages, Postbox will store your account passwords in a hidden file so it won't have to ask every time. You can use a Master Password to encrypt this password database to enhance security, and to prevent the downloading of new messages to your computer. You will be required to enter the Master Password each time Postbox launches, but it will be remembered for the remainder of the session.

Note: The Master Password does not prevent access to email messages, attachments, contacts or other information. The Master Password only protects your account passwords. To protect mail data, we strongly suggest using OS user account passwords.

Setting Up the Master Password

To create a Master Password:

  • Go to Preferences | Options > Security > Passwords.
  • Check the box to Use a master password.
  • A window will appear which allows you to create a password. You can remove or reset your password at any time by returning to this window.

Removing the Master Password

To remove the Master Password from Postbox:

  • Go to Preferences | Options > Security > Passwords and uncheck the option to Use a master password.

Forgot Your Master Password?

If you have forgotten your master password and need to reset it, do the following. Note: this will cause Postbox to forget all of your saved passwords:

  1. In Postbox, type command-shift-j (Mac) or control-shift-j (Windows) to open the Error Console.
  2. Copy and paste the following into the text box: openDialog("chrome://pippki/content/resetpassword.xul")
  3. Press the Return key.
  4. Follow the prompt to reset the master password.
