What constitutes a 'strong' password, and what methods ensure its memorability without compromising security?

A 'strong' password is characterized by its length, complexity, and uniqueness. It should be at least 12 characters long and include a mix of uppercase letters, lowercase letters, numbers, and symbols. It should not be based on personal information, common words, or easily guessable patterns. To ensure memorability without compromising security, you can use techniques like passphrases or password managers. A 'passphrase' is a sentence or phrase that is easy to remember but difficult to guess. For example, 'I love to eat pizza with pineapple!' is a strong passphrase. You can also use a password manager, which is a software application that securely stores your passwords and can generate strong, random passwords for each of your accounts. The password manager encrypts your passwords and requires you to remember only one master password. For example, you can use a password manager to generate a different, complex password for each of your online accounts, and the password manager will automatically fill in those passwords when you visit the websites. This eliminates the need to remember multiple complex passwords while maintaining a high level of security. Avoiding password reuse across multiple accounts is also critical, as a breach on one site can expose your credentials for others.
