UI Terminology: Logon vs Login
Which is the right one to use
- Sign in
- Log in
- Login
Being a non-native English speaker it is difficult to distinguish them. I guess I should have asked at dictionary.com forum but I need a technical answer.
Either of the first two are fine I'd say.
Not the third though - "Login" is a noun (if it is really a word at all): "What is your login?"
The other two are verbs "to sign in", or "to log in".
Either "log in" or "sign in" is fine.
Just make sure you're consistent (see: Login/Logout vs Sign In/Sign Out vs Log in/Sign out – A short roundup.
I've switched to using Sign In/Sign Out/Sign Up for my own apps on the basis that it's slightly less technical language than Log In/Log Out.
Sign In
If you're dealing with an application/website that deals with people
E.g. Sign in to my space, sign in to my blog
Log in
for other applications.
E.g. Log in to the system, Log in on your computer
