We've all been there. You're given a link to a new great product that is going to do wonders for your productivity but when you are done installing it you get a sign up screen that let's you sign up with only two different options.

1. Facebook
2. Twitter

If you're lucky (or not so lucky), you get a third option of Google+. Where's the option to use your email address though?

Opinionated sign ups like this have always been a problem for me. I don't have a Facebook account and I barely participate on Twitter these days, to the point where I am even thinking of deleting my Twitter account. So if I don't have an account for either of these social networks (and yes there are people like this) then what's left for me to do?

It's easy. Give some other product a try that will let me sign up with my email address.

The only time where I will use a product that requires such a sign up is where it allows me to participate on the social network or platform I choose to use.

I've signed up for many products over the years using Twitter, Dropbox and Google. Each time the product was tied to the preferred login that I choose in a way that required a specific login. Journalong uses Dropbox to post journal entries to your Dropbox, Feedly uses Google to sync your Google Reader across, you get the idea. These are specialist products and services that depend on a specific social network or platform.

I will not however sign up with my social network for a product whose only connection to it is to read the list of people I follow on that network and from other networks.

Where a product isn't tied to one social network but offers the choice, I'll always use my email address. If the product wants to connect to my social networks after I have signed up then fine, I'll connect them separately. It means that I can disconnect those social networks at a later date without having to completely stop using the product.

There's a time and place for opinionated sign ups like this but for generic products we should always be given the option of using email.
