Online Banking Protection

The multi-factor authentication (MFA) security feature works 24/7 to protect your online bank account, even when you’re not online. It helps guard against fraudulent login’s and phishing—malicious requests for your personal information, and identity theft. This makes your account harder to compromise because it relies on more than a password for access. You will be shown a security phrase each time you login, to prove to you that you’re at the authentic online bank site and you will register the computer you use to access your account. Any attempts to login made from an unregistered computer will prompt the system to ask for further verification, such as the answers to security questions you set up at enrollment.

Protect Yourself

Going through trash and mail are consistently among the most common ways to victimize someone. The Better Business Bureau recommends that you bank entirely online to protect yourself. That’s why Energy One offers the full suite of online banking options for free. Through 24/7 online banking, you can monitor your accounts in real-time, so you can catch suspicious activity as it happens. Bill Pay keeps your checks out of the mail and your account number private. Notifications and eStatements also keep your account numbers and information out of the mail. Sign up for free and remember that Energy One is here to protect you.
