4 Actions to Take

Use different passwords on different accounts: Do not reuse passwords, as it is one of the leading causes of unauthorized access.
Use the longest password allowed: Use 11 characters or more, a short sentence, or a mix of letters, symbols, and numbers to strengthen your passwords.
Reset your password every few months: Even if you are not prompted to, reset your passwords regularly, especially when these passwords allow access to sensitive data such as banking or medical information.
Use a password manager: With just one master password, a password manager can generate and retrieve passwords for every account you have, encrypting and protecting your online information.

Multifactor Authentication (MFA) is a security measure that doubles the amount of protection on your computer.
MFA involves using a “second factor”—such as the Microsoft Authenticator app, SMS messaging, a landline phone such as your desk phone, or a security token such as a YubiKey—when you log into MFA-protected resources.
Make sure you have at least two authentication methods enabled for your MFA.

Think before you click: Phishing emails and text messages often tell a compelling story to trick you into clicking on a link or opening an attachment. Look for misspellings and poor grammar in emails. These are red flags for phishing scams.
Check the sources before clicking on them: Hover the cursor over a link to see the web address. If it’s different from the URL in the message, it is likely to be a phishing scam. Retype the website address into the browser instead of clicking the link in the email. DO NOT copy and paste it. 
Be careful with your personal information: Avoid providing personal information to unknown people or websites.
Check your statements constantly: Review account statements regularly to ensure all charges are legitimate.

Software updates provide protection against the exploitation of vulnerabilities discovered by hackers. Improving security is the number one reason to update your software.
Regularly check for updates for the operating system on your mobile phones, tablets, and laptops.
Do not forget to update your applications on your devices, especially the web browsers.
Turn on automatic updates, if possible.
