For me logging in was especially troublesome because I have a filter for polygon emails (there are usually enough of them to overfill my inbox) and thus spent some time waiting for the login email until I realized that it is in the special folder.

Upvoted the issue. This feature might be useful as opt-in, but now there is even no opt-out.

This feature is just a quick fix to prevent unauthorized access for those, who use easy passwords. Email is used as a second factor for authentication. A little bit later I'll improve it to make much less obtrusive. Just wait a little.

Weird part is, even now the "Login" button in Polygon can't even be clicked.

when i click to confirm my email message “link has been already used” appeared and nothing change
