Please don't do that. It makes me very angry when I'm trying to quickly get some information from a public/shared device and instead of getting logged in, I get a link on my device. (which I need to retype / send / ...) Most likely I don't care about the security of the account that much in that case. But my email login never goes anywhere close a device I don't own.

Don't annoy users. Just let them log in.
