WM Keyboard

If you use WM Keyboard, its WM Pass tool can type logins from this app, and its code chip can offer the current code when you reach a code box.

It stays off until you turn on Let WM Keyboard fill under Settings, Security. Even then, the keyboard can only ask while your vault is open, and it can never unlock it. Each app checks the other’s signing certificate first.

A password typed this way passes through the keyboard’s process, as anything you type does. If you would rather keep it out of there, use the autofill service instead.
