Security Check Failed error

If you encounter a "security check failed" error, it might be related to your phone's biometric or PIN lock settings.

To resolve this, first ensure that your phone's biometric lock is activated. 

Then, open the Wallet of Satoshi app and navigate to the advanced settings.

Here, you should disable the biometric PIN option. 

Note that this option is only available if your phone's global biometric settings are enabled.

If the problem persists after these steps, please create a ticket and let us know the steps you've already tried.
