Credit Card Account Online Login

If you have a First Security Bank credit card issued prior to June 15, 2108, you may access your credit card information online through 

Debit Card Guard

OUR DEBIT CARD FRAUD PREVENTION SERVICE sends text alerts to your mobile phone when specific activity occurs on an enrolled First Security Bank debit card.  If the transaction is fraudulent, reply to the text as directed and all further transactions will be stopped and the card will be blocked until you can be reached by telephone.

Fraudulent activity can be recognized and stopped right away which significantly reduces the likelihood that additional unauthorized transactions can be made.  Once you successfully enroll in the anti-fraud service, a text message will be sent when a debit card transaction occurs that meet any of the following criteria:  

  • A transaction was conducted without the debit card being present (ie: phone or internet purchase)
  • A transaction was attempted, but declined
  • One or more transactions totaling more than $500 was made in one business day
  • A series of transactions were made exceeding 5 in one business day

 HOW TO ENROLL - Have your debit card information available, CLICK HERE and follow the instructions.

You may register an unlimited number of Big Sky Western Bank debit cards. Once a card is enrolled you will receive a confirmation message similar to the following:

"Welcome Verizon customer to CardGuardian.  For help please visit (The provider is your mobile phone provider ie. Verizon or AT&T). 

You may stop the alert messages by replying "STOP" to any text message.  Reply "HELP" for assistance.

Multi-Factor Authentication FAQ's

What is Multi-Factor Authentication (MFA) security?
MFA security is a second layer of security that is added to protect users from the growing number of internet security threats. This second layer of security combined with your login ID and password represent two factors in logging in to our internet banking system.
Do I have to use MFA security?
Yes, for your protection, First Security Bank automatically adds this security feature to your internet banking service. This second level of authentication helps to prevent the possibility for online fraud. One common method of fraud involves impersonating members through the sign on process. If fraudsters cannot receive the secure access code, then they can’t access your internet banking account.
Should I register a public computer (coffee shop or library)?
Users should not register a public computer. If a computer is registered, the fraudster only needs to get the users login ID and password to be able to access your internet banking account.
Can I register more than one computer?
Yes, you can register more than one computer. We do not recommend registering public computers.
How do I un-register a public computer?
Our CSR’s can un-register a public computer in our system.
If someone steals my password, will the system prevent them from accessing my account from a different computer?
If your login ID or password are known by someone else, it is important we change your password and possibly your login ID. In order to access your internet banking account, the person would need to have access to the telephone number or email address on file with the bank to receive the secure access code.

Security Tools & Tips

Mobile Banking Security

Invest in an antivirus application for your mobile device to help protect you when downloading apps or mobile content. Never provide personal identification or banking information over your mobile device unless you initiate the contact and you know that you’re dealing directly with your bank. Never share your password, account number, PIN and answers to secret questions. Don't save this information anywhere on your phone. Never set the app, web or client-text service to automatically log you in to your bank account. If your phone is lost or stolen, someone will have free access to your money. Set the phone to require a password to power on the handset or awake it from sleep mode. Remember, your bank would never contact or text message you asking for personal or banking information. Assume any unsolicited text request is fraudulent. Giving this information places your finances and privacy at risk. Immediately tell your mobile operator and your bank if you lose your phone.
