Two-Factor Authentication (2FA)

Online Banking uses two-factor authentication (2FA), which means that on each and every login, it is verifying two out of the following three methods of authentication:

  • Something you know, like a password
  • Something you have, like a phone or other device
  • Something you are, like Face or Touch ID

This helps protect customers in the event that a password is compromised. Even when a customer is using Face ID, it is still verifying the device behind the scenes as the second factor.


Do not share a verification code with anyone. Our Employees will never ask for your verification code.

First Time Sign Up

When a customer signs in for the first time, they are prompted to select their verification method.

  • Authenticator App Most Secure
  • Text Message
  • Phone Call

Authenticator App

Most free authenticator apps are supported, but we suggest Authy.

Customers will be prompted to provide an email and phone number.

If you do not have your chosen authenticator app downloaded, you will be required to do so before you can get a verification code.

We will request the verification code. To retrive the verification code you will need to open your authenticator app and copy/paste or enter code.

Text Message

Enter your number and hit Next. A code is sent shortly after.

Please note that the sending phone number can vary, and will not match our toll-free number.

Enter the code that you were sent. After successfully entering the code, you're all set! On subsequent logins, you can choose to have your device's browser remember you so that you're only prompted on new devices.

Phone Call

If you do not answer the phone, a second call will not be made. The system will not leave verification codes on voicemail.

Edit Settings

You can also manage your authentication settings after logging in

After you log in, navigate to your user name, then Settings, then Security.
