The toolbar is not accessible by the keyboard because of technical restriction. See this comment to more details.

Things i am missing here:

• Navigation through buttons is correct, but, numerical keyboard should work as well. User should be able to type/delete the passcode with the physical keyboard in the same way as clicking buttons.

• Navigation through buttons is a keyboard trap in the settings. I did not find the way to jump from the buttons to the topbar, in case i want to cancel the view

• Are the focused buttons with the keyboard fulfilling contrast requirements?

Now It should work.

Try again. With my external keyboard the ESC key is working. But I added something else. Let´s see.

• Are the focused buttons with the keyboard fulfilling contrast requirements?

No, It is not meeting the contrast requirements

After last commit:

• typing numbers with physical keyboard is now posible. Numbers are displayed while typing. It'd be better not to be shown but this is not a big problem

• Esc works to dismiss the view 💯

About contrast requirements:
Here we have the same problem that we had in this issue: #4369
If we change the focus color to black, the only contrast requirement that the 4.5:1 meets is the blue of the button with the white of the view. The other colors do not meet this contrast requirements.

If we do the same test with the gray of the background, this would be the result:

On the other hand, the contrast between the focused and unfocused state does not meet the recommended contrast ratio either (at least 3:1). For example, if we focus on the blue of the buttons:

To give you an idea of ​​what the final result would be in the application with the focus to black:

Let's move the contrast thing to the global topic, then...

this one is approved, at least for a first iteration.
