Rather than passively saying 'verify this login from another device', we should give the user an explicit button to press to select to verify based on another device, as opposed to entering the recovery passphrase/key. Psychologically I think this will help the user realise they need to do something to verify the new login.

Relatedly, pressing the button should re-trigger verif prompts on other devices by sending a new verif request out in case they were cancelled (this is #13186 though)
