Mobile App - Two-Factor Authentication (2FA)

Yes. You can get locked out of the enrollment process if too many attempts are made with an incorrect verification code (more than six times in a single hour). You must wait an hour to try again following your first attempt. If you make more than 20 unsuccessful attempts in a 24-hour period, your login will be 'Suspended' and you will not be able to attempt again for 24 hours. If you have questions or need additional assistance, please contact our Member Assistance Center at (913) 599-1010 during our regular banking hours for assistance.

Codes sent by email are not available, but can be received using one of the following options:

  • Text message

  • Phone call

  • Authy App (A third-party app that generates a one-time passcode. To register you will need an email address and phone number.)

You can reset your own two-factor authentication enrollment in both the app and online by going to your Profile page, then select Security within the Settings area.

Two-Factor Authentication (2FA) is a security feature that helps safeguard your account information. To implement 2FA, you will need to enroll an email address and a phone number (mobile or landline). Once this information is entered, you'll choose one of three options to receive a one-time verification code:

  • Text message to the mobile phone entered, or

  • Automated phone call to phone number entered, or

  • Authenticator App. Download the Authy app

After entering the verification code from a secure computer, you have the option to select "Don't ask for code again on this computer." This allows you to avoid entering a verification code during each login. This option should never be selected on a shared or public computer.

If you select to receive a phone call (cell phone or landline), you will enter a single specific digit, as directed, before the verification code is provided. Caller ID will show as "Digital Banking".

If you fail to answer the authentication phone call, you will need to select the option to have the code re-sent. The system will not leave codes on voicemail.

Note: The phone number used to send the verification code may not always be the same phone number but will always be sent from a US-based phone number.

Codes will expire within three minutes.

Yes! If you’ve added more profiles to your mobile app, you will need to set up 2FA for each of them. If the account has already enrolled in 2FA, you will need the verification code sent to that user.

There are several reasons you may be prompted for a verification code. This may include:

  • logging in using different browsers

  • deleting your browser history

  • you have set your browser settings to delete your cookies and history automatically

Please be sure the phone number you entered is correct. If it needs to be changed, contact our Member Assistance team at (913) 599-1010 during regular business hours.
