About this app

The ČSOB Smart Key will make it easier for you to log in and confirm payments in internet banking, as well as card payments in e-shops, or remote verification when calling the Infoline or a bank branch. You don't have to wait for a confirmation SMS and then rewrite the code from it. With the Smart Key, notifications will pop up immediately and you will confirm the request with a fingerprint or numerical PIN.

Why to use ČSOB Smart Key application:

  • Conveniently log in and confirm the payment in internet banking

  • You can just as easily confirm a card payment on the Internet

  • Remote verification when calling the Infoline or bank branch comes also very handy

  • You can use a fingerprint instead of a PIN

  • Authentication complies with bank-grade security standards

  • Being offline is not a problem: app works also offline for confirming transactions in internet banking

  • A map of branches and ATMs is a part of the app

  • You can install it on both your mobile phones and tablets



After downloading, simply activate the application using the activation key ftom internet banking, ATM, or branch.

Works (so far). Utterly lacking in security, even though you are forced to use it. You can choose to login with biometrics, which is laughably easy to misuse by a malicious party gaining possession of your phone, or a five(!) digit PIN. Five digits exactly, mind you, you can't even pick something longer and thus at least marginally more secure. The idea that all someone needs to steal my money is either a finger, or a simple five digit code is frankly terrifying.

You have to go to the bank by yourself when you forget password. Any other bank has this better.
