Problems with revealing password keys

Hi everyone does anyone know why I can't reveal my owner keys or any other password keys in my settings?

I put the username and password but it's still shows row of black dots on the password it didn't reveal anything.

If anyone knows how to reveal please let me know in the comments section below. I've been check online how to do it seems like a lot of people have this problem as well.

Mine can't seem to be revealed for some reason.
Hope someone can explain this thank you. looking forward to your help.
