5. Sign In Forms
Don’t innovate on the sign in forms. Use common practices to allow the user to get in
Easily and faster. Provide a way to retrieve a forgotten password.
9. Registration/Sign Up Forms
Registrations should have minimal inputs. Edit ruthlessly. Remove Confirm email and Confirm Password fields.
Horizontal fields could end up truncated. Avoid them.
