On the backend secure_backup_setup_methods is set to passphrase. Due to the bug app still allowed to select Security Key when setting up backup.
The issue was that code loading the methods was executed after the BootstrapStep.FirstForm was created, and the step was not updated

        viewModelScope.launch(Dispatchers.IO) {
            val wellKnown = rawService.getElementWellknown(session.sessionParams)
            setState {
                copy(
                        isSecureBackupRequired = wellKnown?.isSecureBackupRequired().orFalse(),
                        secureBackupMethod = wellKnown?.secureBackupMethod() ?: SecureBackupMethod.KEY_OR_PASSPHRASE,
                )
            }
        }
