I got the following screen when logging in to Google (to use a third-party service) and I was glad to see it. I can’t remember the last time I saw this, but I think it’s something Google should show more often.
If you want to deal with this information right now, you can log into Google, go to My Account, and then Personal Settings, and then click on Change password recovery options.
