The sign-in code is sent as soon as you enter your email

Improvement Dashboard

Signing in with an email code is one step shorter. Enter your address and the code is already on its way, so the code page opens with the field ready for it rather than asking you to press “Send code to email” first.

The page also says where the code went. A mistyped address is now something you can see, instead of something you work out from mail that never arrives, and “Wrong email address? Change it” takes you back to correct it.
