Digital Secure not working on IPhone 14 Pro, MacBook Pro

[OldieButAGoodie]

After downloading Digital Secure and adding my first 2 devices, I immediately lost access to all my financial, email, other most important accounts.  My repeated correct passwords and verifications in attempts to sign in just go into a never ending loop and never opening any.  This is a NIGHMARE!!  I am really in a bind and cannot get any help from Verizon except a useless chat suggesting I call during business hours.  How do I back out all this invasive so-called "security" that has made my brand new iPhone and my trusted, never a problem MacBook virtually useless to manage my finances, my email, etc?
