Financial apps like Coinbase, Venmo, and Cash App require weak 4-digit PINs alongside biometric authentication, creating significant security risks. If Face ID or Touch ID fails, these apps fall back to the weak PIN instead of your username and password. Meanwhile, apps like Fidelity and Schwab get it right by avoiding these pitfalls.
Have you filed a CFPB complaint regarding these weak authentication implementations? If not, I recommend that you do so.
