To change your 2FA authentication method from SMS to TOTP (authenticator app) in the mobile application:
Tap the profile icon in the top-left corner.
Go to Security → Two-Factor Authentication.
Select Authenticator App and follow the on-screen instructions.
You will be prompted to download an authenticator app (e.g., Google Authenticator or Microsoft Authenticator) from your app store, then either copy the key or scan the QR code.
Enter the generated 6-digit code from your authenticator app into the XTB app to confirm the change.
Before completing the process, backup codes will be displayed. These codes can be used if you encounter login issues. Each backup code can be used only once, so make sure to save and store them in a secure place.

Important: Remember that the above change of authentication method is only possible if you have current access to your account - i.e. your current phone number in the system is correct and you can easily receive SMS messages to it necessary to authorize the process.
If you don't have access to your account (e.g., due to a phone number change) or are having general difficulties logging in (not receiving SMS codes), the above self-configuration won't be possible. In such a situation, please contact our customer service immediately to verify and update your details
