Passwords should be protected against compromise using appropriate tools and policies. One tool is a password manager, which is a secure storage location for all your different passwords. A password manager protects its contents by using a “master” password which should obviously be very strong. A good password manager can also generate secure passwords for you.
A password manager can either be installed locally on your computer or you can access the information from a cloud-based manager. Locally stored password managers should be backed up regularly in case of corruption. Cloud based password managers have the added advantage of being able to access passwords from multiple devices. Accounts can be further strengthened using Two/Multi Factor Authentication (or 2FA/MFA), where the method used can also be stored in the Password Manager.
