Why do banks have 2FA through SMS and not through authenticator apps? ›

What is the advantage of SMS 2FA over other authentication methods? An advantage of SMS 2FA over other authentication methods is that it does not require the user's phone to have internet access. This gives SMS-based 2FA an edge over other methods that rely on online connectivity.

An authenticator app is safer than SMS authentication because it generates 2FA codes locally, which prevents cybercriminals from intercepting the codes as they can with SMS.

It is more convenient and at least as secure as email 2FA, and better than SMS. It's important to realize that for banks IT is a cost center. They spend only the absolute minimum for IT, because they don't make money with it.

2FA can be vulnerable to several attacks from hackers because a user can accidentally approve access to a request issued by a hacker without acknowledging it. This is because the user may not receive push notifications by the app notifying them of what is being approved.

Once you have entered your password, an authentication code is sent via text message to your mobile device, which you can then enter on the website or application to complete the authentication process. Scammers can get around SMS-based 2FA by using social engineering to get you to send them your code.

1. Biometric Authentication Methods. Biometric authentication relies on the unique biological traits of a user in order to verify their identity. This makes biometrics one of the most secure authentication methods as of today.
