Upwork security - To log in from one pc at a time

[#1]

Can i put a security of some sort on my upwork, that whenever i am logged in from one pc, it won't allow me to log in to any additional pc? but doesn't effect my mobile?

No such functionality exists.

Hi Mubariz,

There is currently no option to do this that will lock the access to one device. You might want to consider reading about Upwork's Two-Step Security Verification.
