This is a short recipe how to add the functionality to a Hobo powered Rails application to login via access to an email address.

Disclaimer:

I thought about security concerns regarding this.

The only drawback compared to an application that lets you change a forgotten password is that this way, you wouldn't notice if somebody logged in with the stolen login link, because there is no need for a password change.

I'm no security expert. If you are :-), feel free to add comments to this gists, that help me improve security.
