Can I sign in without my smartphone?

Yes, you can sign in without your smartphone. There are two possible methods for you to sign in without your smartphone. 

1. You can use someone else’s smartphone, such as your colleague’s smartphone. If you are using someone else’s smartphone, make sure to unselect “Remember me” when you sign in. Otherwise, your colleague will be able to sign in as you in the future. 
2. If the site has set up a kiosk, you may be able to sign in using it. Read here for help on using site kiosk to sign in. 

Although you can sign in without your smartphone, using your smartphone to sign in is safer because you do not have to handle someone else’s smartphone. More importantly, it is more convenient because, after you first sign in, our software automatically recognizes it during your subsequent sign-ins.
