Our Guardian Text Alerts service has been discontinued. We apologize for the inconvience.

You can easily manage and protect your Sentinel Federal Debit Card and Credit Card from fraud using the “Manage My Cards” feature in our Mobile App.

Not only can you lock and unlock your card any time, for any reason, you can also get an Activity Alert push notification when any transaction is made using your card.

Simply login to our app and select “Manage My Cards” in the More Menu.

If you have questions, please give us a call at 605-923-1405 or 888-923-1400.
