You can use your mobile as well via the browser (not the APP) so long as you have control of the IP address. An easier method is to just check your email on your mobile though.
As a general rule your best not logging on from your work if its a shared internet access point or computer. Again just check emails
Don't think logging in from a remote location every once in awhile will do much harm. I've done it with regularity at different points. Even from a Starbucks, as long as one has a record of logging in from a stable user account where cookies are never erased. Now if one starts logging in from a remote location out of state and starts listing a lot that could draw red flags. But even then it would probably be a request to call in or some other verification.
That doesn't mean one can ignore basic account security like "not" using the same user acct. or IP to log into multiple accounts etc... .
Depends on what you do when you go online. Often I am not asked to log-in again until I try to list, edit or something possibly considered more serious threat.

Even one time COULD lead to issues - why risk it for a Starbucks connection? I wouldnt.
