You are worried about your password being stolen, but you have had this password for a long time. It is a good password and hard to remember. You still want to use some form of this password in your new password. What should you do?

You should use a password manager to generate a new, secure password that is based on your old password. This way, you can keep the same structure and complexity of your old password, but with a different combination of characters. A password manager can also help you store and manage your passwords securely.
