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

Even though you want to reuse a part of your existing password, it is generally recommended to create a new password from scratch to ensure maximum security. However, if you insist on incorporating your current password into the new one, you can follow these steps to modify it effectively:

1. Start with your existing password as a baseline.
2. Consider adding extra characters or numbers at the beginning or end of your password. For example, you can add a symbol like an exclamation mark or a number.
3. Incorporate capitalization into your new password. You can capitalize the first letter of each word or just some specific letters.
4. Replace some characters with similar-looking symbols or numbers. For instance, replace 'a' with '@', 's' with '$', 'i' with '1', 'o' with '0', 'e' with '3', etc.
5. Consider adding a variable component related to the website or application you are using. For example, you could add the initials of the site or specific letters related to the account.
6. Ensure your new password is long enough and uses a strong combination of letters, numbers, symbols, uppercase and lowercase characters.

Remember, it is best to use a unique password for each account to minimize the risk of password theft. Using a password manager can help generate and securely store strong, unique passwords for every account without the need to remember them all.
