Don't show pin?

I unlock my phone (Huawei Mate 20 Pro) with a PIN. If I enter this in the lock screen, it is shown briefly in the display as a number and then as a point. How can I set that only one point is directly visible?

You can find it in the security settings. Then there's "Visible password".

Thank you very much.

That always annoyed me and then I found this function by chance. But I can tell you one thing. Since you mistype more often because you do not really see what you are typing…
