This was the message from Matt Cutts webspam team lead at Google back in 2010 and we think that nothing has changed. However, things have changed since 2010. I think that it is even less relevant to use nofollow than yesterday for several reasons. People use google to find pages on your websites. They don’t use search fields anymore. So for instance, if they look for a login page on sitecozy they will type “sitecozy login page”. This would be the same with terms of service pages. Also, we use templates. There are many login pages where there are important links can be found on the page. For example, there is maybe a link to the homepage, to category pages. It is more important to focus on the outgoing links that can be responsible for a Google penalty. Those ones require a nofollow. I think about ad links, paid links or affiliate links.
