Login vs Sign In
Share this on Twitter
If you develop web apps or design web app interfaces there is one link you will inevitably always have. This link allows the user to log in, or sign in, to the website. But what is the correct terminology to use?
A look at the big sites
Let’s look at the web’s top web sites and applications to see what terminology they use.
Login: 1 Sign in: 0
Login: 1 Sign in: 1
Login: 2 Sign in: 1
Login: 2 Sign in: 2
Login: 2 Sign in: 3
Login: 2 Sign in: 4
Login: 2 Sign in: 5
Login: 2 Sign in: 6
Login: 3 Sign in: 6
Login: 4 Sign in: 6
Login: 4 Sign in: 6 Log In: 1
Login: 4 Sign in: 6 Log In: 2
Looking at other websites there doesn’t seem to be anything decisive – there’s a mix of login, sign in and log in.
What does each term mean?
Definition of login (from Dictionary.com)
the act of logging in to a computer, esp. a multiuser computer or a remote or networked computer system
Definition of sign in (from Dictionary.com)
an act, an instance, or a time of signing in
No conclusive answer here either, both work fine.
How I work
I use login.
The reason for this is because I tend to keep sign up and login links available at all times, on all pages. These links are usually top right and next to each other e.g. Lookaly.com
Here’s a heatmap visual of this area.
Using the term ‘login’ means that at a glance the user can instantly tell the difference between ‘Login’ and ‘Sign up’.
By using ‘Sign in’ the user has to take a second or two to read the words to identify between the two and there’s more chance of them clicking the wrong link.
Of course this theory only comes into effect if you have a sign up and login link beside one another. As you can also see from the heatmap above, this sign up link doesn’t get a lot of clicks and most of the sign ups come from other call-to-actions throughout the site.
