About Czech Bank iD

Czech Bank iD is a digital identity verification solution designed to streamline online authentication processes in the Czech Republic. Registered users can log in to digital services using their bank credentials in a convenient and secure way.

By leveraging bank-level authentication, Bank iD minimizes the risk of identity fraud while enhancing user experience across platforms. In the Bank iD scheme, banks act as trusted identity providers (IdP) by verifying the identities of their customers through secure login methods.

Bank iD is available in Czech Republic for holders of a bank account at one of the participating banks.

User journey with Bank iD​

End-users wanting to authenticate with Czech Bank iD typically follow these steps:

  1. The user chooses their bank.
  2. The user logs in to their bank's website in the same way as they normally log in to their online banking.
  3. The user confirms their login with a second factor, either in the bank's mobile application or by entering a code they received by text message.
  4. The user agrees that the bank will transfer selected personal data to the service provider (your application).
  5. The user identity is verified.

End-user personal data​

End-users that successfully complete authentication sessions with your application through Czech Bank iD agree to sharing their personal data with you. You rely on this information to verify the identity of new users and authenticate existing users.
