Is Mobile Banking secure?

Text Banking Security

Each text message request authenticates separately by checking that the mobile number of the device used to send the request corresponds to the device number registered for the user initiating the transaction.

Account values used by text commands are the account nicknames used within Internet Banking or masked account numbers.  They do not contain any unmasked account numbers.

Web Browser Security

Mobile Web Browser Banking (XHTML) uses the same security infrastructure as Internet Banking including:

  • HTTPS encryption with 128-bit AES public key encryption certificates for all traffic between the mobile device and the internet and Mobile Banking servers.
  • Connection via secured-socket layer (SSL)
  • No data or application pages are stored on the mobile device with each page being retrieved on-demand.
  • Authentication is session-based using a Mobile Login; Mobile PIN and the same MFA (Multi Factor Authentication – which is our challenge question process) used for Internet Banking to authenticate the user for the duration of the browsing session.
  • Mobile Password 3-Strike Lockout.  You can unlock yourself by changing your Password within Internet Banking.

What can I do to keep my information safe when Mobile Banking?

For your security, you should:

  • Use a different Login for Internet Banking than you do for Mobile Banking
  • Set up nicknames to avoid having to send actual account numbers or other sensitive information via text message
  • Delete all text messages from your mobile phone after viewing
  • Keep your mobile device’s operating system up-to-date

*For assistance, please contact the merchant where you purchased the mobile device or your mobile carrier.

  • Install anti-malware software for Internet browsing on your mobile device
  • Click on the LOGOUT button after each Mobile Web Browser Banking session
  • Use the mobile device’s Passcode/Password Screen Lock functionality, if available.
  • Setup email alerts in Internet Banking to monitor account balances
  • If using a smart phone, install an app that wipes your data remotely in case the device is lost or stolen.
  • Not allow your mobile device to remember login credentials.

Please Note:

  • Mobile Logins are not case sensitive but Passwords are.
  • Challenge questions, images and phrases are the same ones used for Internet Banking
