How do I use Safari integration on iOS?

Before using it, you need to enable pwSafe's action extension. To do that, tap the share icon and then select the rightmost ellipsis icon on the black and white icon row. Enable pwSafe in the list which will pop up.

Then, whenever you need to autofill a form, create a new password or change an existing one, tap the share icon and then the black and white pwSafe icon. You may move that icon to the left by tapping, holding and then dragging it with your finger.
