@AngelaScholder : so do I on my Windows PC.
On my Android phone I'm using KeePassDX and on my iPhone KeePassium.
Unfortunately Google recently broke part of Autofill in Android. I had to enable "MagicKeyboard" to make things work again.
When logging in to security.nl, I now have to tap the globe-icon at the bottom right of the screen to change "keyboards".
Then the regular keyboard is replaced by the more or less "Magic Keyboard" dummy keyboard, which pops up the green KeePassDX prompt as shown below (the red text was added to the screenshot by me).
Autofill means that I don't have to use the clipboard and more importantly, that I'm less likely to try to log on to a fake website.
