- Enter the master password.
- Now copy only the domain and the username into some document that is easily available to you.
- Use the calculated password for this domain.
- Whenever you need to reenter the password, recreate it by checking your list, and reenter the same data.
At some companies you need to change your password frequently. For this, use different domain names for each password.
