About this app

The KB Klíč app verifies your identity and safely logs you into MojeBanka online banking and Komerční banka's other online apps. You don't have to enter a texted code and you also authorise payments through the app.

You need the following for KB Klíč activation:
- KB ID, which you will find in the Electronic Signature Agreement. You can also use your username/email
- An activation code that you will receive at a KB branch or when you log into mujprofil.kb.cz otherwise than via KB Klíč

The activation guide is available at

Set the PIN on the occasion of activation. You can set up your fingerprint if your phone supports them. Komerční banka will never see your fingerprints; they are retained in a secure repository in the phone.

If your phone is connected to the internet the request to confirm the activation will be received automatically in your phone. Check and confirm the request. If offline, select 'The device is not connected to the internet' option in your computer. Using the KB Klíč app, scan the pictorial code from the computer's screen. Then confirm the code by the PIN or fingerprint. Finally, type the generated code in your computer.

Please note: If you enter an incorrect PIN five times KB Klíč blocks access. You will then activate the apps using an activation code that you will receive in an ATM, at a KB branch or after logging into mujprofil.kb.cz otherwise than via KB Klíč.

KB Klíč will not work for you if you have reinstalled software on your phone and your platform (root) is therefore not protected. All of this for the sake of security.

Reason for existence of this app very much unknown. Money down the drain. Foreign online banks manage security in much smoother way e.g.: N26, Revolut, Trade Republic, etc.

Negativní zpětnou vazbu ke KB klíči spíše neregistrujeme, přesto díky. Obecně je bezpečnost přístupu hlavní prioritou a trendy bedlivě sledujeme. Díky

The app keeps saying there was a new fingerprint entered (and disables the fingerprints) while there was no attempt to enter any fingerprint. I think that it is a bug and it makes me feeling uncomfortable - if there are bugs, how secure it can be? It also does not help that the bank dismissed my concerns, saying that observed incidents somehow prove app's security. Such BS! Obviously, they have no idea what they are talking about... I am going to file a complaint. No doubt about that.

Co máte na mysli kompromitací? Asi že by se někdo fyzicky dostal k Vašemu telefonu a zkoušel se přihlásit? Pokud ano, pak by to naopak důvěru mělo posílit. Jako pravděpodobnější ale vidíme problém se čtením otisku, ale nevadí. Kdyby došlo k blokaci otisku, stále budete vyzván k zadání hesla.

it wouldn't allow me to finish activation. it switched between 2 messages telling me I have no internet connection and that I've input wrong data... and this is when I'm creating a password and the klic is already activated. I clicked back and now can't finish the activation cos I don't have the ID and SMS code as on my computer it finished the process and now is asking for my password to log in. which the app wouldn't let me create.
