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
https://www.kb.cz/en/new-login-methods#kbklic

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.

Reliably does what it says on the label. But some simple UI improvements would go a long way in making this app better, e.g. immediate pairing of requests based on a single unique code (MojeID-style) or immediately closing the app when there are no more pending requests.

Proč ne? Díky za tipy Juraji a rádi je zvážíme.

The numeric keyboard (for inputting the PIN) is *vertically* very small. I have to retype more than half of the times. I often "mistype up" or "mistype down", i.e. 1<-> 4 or 2<->5 or 3<->6. It seems this is an aesthetic decision but at the expense of usability.

Mrkneme se na to a pokud to půjde, určitě v některé z dalších verzí zvážíme úpravu. Díky za zpětnou vazbu!

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.
