Many scams originate right at your fingertips through your computer or smartphone. The good news is the way to block them is also within your grasp. Here are three tips to keep your devices safe from criminals.

Make sure your devices’ operating systems are up to date; you should be able to set an auto-update feature that downloads the latest software when available.

Next, make sure to change the password on your Wi-Fi router so it’s different from the password it came with. If you have a lot of devices connected to it, they could be vulnerable if the router is compromised.

Lastly, a password manager is a great way to create unique and hard-to-guess passwords for all of your online accounts and apps.

Be a fraud fighter! If you can spot a scam, you can stop a scam.
