A conventional authentication system relies on two forms of identification to prove your identity: your login ID and your password. Multi-factor authentication uses multiple forms of identification to make it harder for attackers to access your account. The multiple forms of identification can include something that you know, such as a password, and something that only you have.

In online and mobile banking, we can send a secure access code to a contact address that you configure. The code is only valid for a single use and it expires after a short time. You choose one of the following ways to deliver the code:

Method Details

eMail

The system sends an email message with the code.

Phone

The system calls the telephone number on file. You answer the phone normally and make a selection to hear the code. If necessary, you can repeat the code. The system does not leave the code on voice mail. If you miss the call, you can request a new code.

Text (SMS)

The system sends a text message with the code. Standard text messaging fees apply.

 If you have never used a particular browser or device to log in, you may need to enter a secure access code to use it. If the browser or device is one that you plan to use again, you can register it. By registering a browser or a device, you confirm that it is under your control and that you intend to use it to access in online banking or mobile banking.

Tip:  Multiple users can register the same browser or device.

You will need to register your browser or device again in the following circumstances:

  • You use a different browser on your desktop.
  • You delete and reinstall the mobile banking app.
  • Your browser does not save browser cookies.
  • You clear existing browser cookies.
  • We reset registration for all users for security reasons.

Caution:  Only register a browser or device if it is under your control. Do not register a browser on a public computer.
