The necessary updates in the Outbank app have already been completed. You’ll just need to enter your new login details (Sparda Netkey and Online PIN) in the app:
‘Settings’ > ‘Bank credentials’ > ‘Select Sparda-Bank login’ > ‘Add your new credentials’ > ‘Done’ > ‘Update configuration’

Important Note: If you've been using a 6-digit online PIN, you'll need to update it on the bank's online banking site to meet the new security requirements. Your new PIN must be at least 8 characters long and can be up to 20 characters.
