change PIN code

Hi @kreisler! It sounds as if you're referring to your Windows Hello PIN. If so, this can be changed in your Windows settings by following the steps in the Microsoft Support guide below:

• Change your PIN when you’re already signed in to your device - Microsoft Support

It's important to note that when using Windows Hello unlock with 1Password, it's possible to unlock 1Password with your Hello PIN alone. As such, we highly recommend making sure that your Windows Hello PIN is strong and alphanumeric: Protect yourself when using Windows Hello

I hope this helps, but if you have any further questions, let us know!
