Another user has enabled apple notification on CHASE app

Like I said, this is a standard warning, and when another device (someone) activates something that is different than what it used to be, it sends that warning. Poorly worded as others have said, it just did not know it was you, because it was a different device. It needed to know you first. If you are concerned, you need to contact Chase and ask them. Let them know that you have downloaded the app on a new device and were just signing in. They can explain their features.

There have been several posts reporting this same message recently from people who got new phones.

I suspect deggie is correct.

If that isn't the case, and you have never used the chase app tied to your account on any device, there may be a wee issue with Chase itself as this may be a false alert, or at least a badly worded alert on their part.

I believe that Chase is using the mac address on the device to identify users. I know if I go to use a different device to log into my banking app, they send a code to my trusted device for me to enter so that it can verify it is me and then put a cookie on that new device. They are using cookies to help identify the trusted devices.

Were you using the Android version of the Chase app with your other phone using the same phone number?

You're welcome.
