Cybersecurity best practices emphasize MFA and regular password updates

Cybersecurity experts emphasize the importance of multi-factor authentication (MFA) and regular password updates to protect digital identities against increasing cyber threats like phishing and brute-force attacks.

MFA enhances security by requiring two or more different types of verification factors. These categories include something the user knows (passwords or PINs), something the user has (physical devices or authenticator apps like Microsoft Authenticator and Google Authenticator), and something the user is (biometrics). While SMS-based codes are common, more robust methods include physical security keys and passkeys.

Additionally, regular credential updates are recommended to mitigate risks from data leaks. For critical systems such as banking and corporate servers, experts suggest updating passwords every 90 days or immediately following a suspected breach. Personal accounts, such as social media and streaming services, should be updated every six to twelve months to prevent widespread unauthorized access caused by password reuse.
