Regular e-mail is unencrypted and not secure; sensitive information should not be sent via that channel. Messages travel across many networks before reaching their final destination, enabling prying eyes to eavesdrop on e-mail messages.

Scam and Fraud Alert

Please remember that Star One employees will never call you to verify or ask for your personal information.

Hang up immediately if someone claiming to be a Star One employee asks for any banking information—such as your Online Banking login information, account numbers, card PINs, or one-time passcodes.

A fraudster may try to reassure you that it's OK to share your information—please hang up, it's not OK.

Several Star One members have received phone calls from a person claiming to be a Star One employee—with a caller ID forged to look like a Star One phone number—and whose goal is to gain access to members' bank accounts online.
