Given the pros and cons of password expiration, what are some best practices to follow for computer security? To ensure the security and usability of your passwords, it's important to use a password manager, multi-factor authentication, and follow password hygiene. A password manager can generate, store, and fill in your passwords for various accounts and devices. This way, you only need to remember one master password to access your password manager. However, make sure you choose a reputable and secure password manager, and protect your master password with a strong passphrase and a second factor of authentication. Multi-factor authentication (MFA) requires you to provide more than one piece of evidence to verify your identity when logging in to an account or device. However, be aware that some MFA methods are more secure than others, and avoid using SMS or email as your second factor as they can be intercepted or compromised. For password hygiene, avoid using personal or common information in your passwords, such as your name or birthday. Additionally, don't reuse the same password for different accounts or devices as this can expose you to risk if one of them is compromised. Additionally, if you suspect or confirm that your password has been stolen or leaked, change it immediately instead of waiting for the expiration date.
