Online Banking Security Upgrade

Share:

During the week of April 20, we will be undergoing an update to our online banking security tools designed to enhance both protection and your overall experience.

What’s happening?

During the week of April 20, we will be upgrading our Multi-Factor Authentication (MACO) system. The work will take place primarily during off-peak hours on Tuesday, April 21 and Wednesday, April 22.

What to expect:

  • Temporary interruption: Some MACO features (such as biometric login options like fingerprint, face recognition, voice authentication and PIN) may be temporarily unavailable during the migration.
  • No disruption to account access: You will still be able to log in to online banking using your username and password.
  • Re-enrollment required: After the upgrade, most members will be prompted to re-enroll in their preferred authentication methods.

What you need to do:

  • During the migration: Simply log in with your username and password.
  • After the migration: Follow the prompts in the mobile app to re-enroll in your preferred security features.

We appreciate your patience during this transition as we continue to improve your digital banking experience.

If you have any questions, please don’t hesitate to contact Sentinel Federal Credit Union at 605-923-1405.

What Our Members Say About Us

“We have several credit unions that got lost in the mix during a move–our bad. However, out of all of those credit unions, SFCU went OUT OF THEIR WAY to ensure we knew our account was dormant and helped us through the process of getting the account back on track. They also refunded every fee taken for dormant status. After losing more money than I’d like to admit from other institutions, I cannot tell you how much I appreciate the customer service of Sentinel FCU.”

“I worked with Dane to open a business account. Dane took the time to explain all the documents I’d need in advance. The appointment itself went smoothly, and it was a very quick and easy process. Dane was able to answer all my questions. I am happy with this branch’s customer service. The turnaround time and benefits (no high minimum balance or additional fees) honestly can’t be beat by any other bank. Highly recommend.”

“I have been using Sentinel for almost 30 years, and my family has been just as long! I purposely make the extra drive to work with Nate! Not only has he always been on the ball of my personal account, but my business account! He has resolved issues with other banks in a timely manner when he didn’t have to! Every time I go on he always has a smiling face and is easy to work with.”

“If you’re in the Rapid City area and you’re looking to drop the elbow off the top rope, Macho Man style, then look to Sentinel Federal Credit Union! Their customer service is off the hook and when you call you never get a robot or an automated answering machine! I don’t think I’ll trust another big bank with my money for as long as I live! By the way, I don’t even live in South Dakota!”
