We love two-factor authentication, and we love services that make our text messages accessible from our computers. However, if you don't want anyone else -- a snooping spouse, child, parent, or most importantly, a laptop thief -- getting hold of your private information, you might want to alter how you use two-factor authentication.


Whether your files are stored on Dropbox, iCloud or Mega, they could do with a little more security. It's impossible to make them "hack proof", but there are a few steps you can take to make your data as secure as possible -- and still convenient to access. Let's walk through those steps.


Dear Lifehacker, I am quite security-conscious when it comes to online accounts and use strong passwords via LastPass and two-factor authentication wherever possible via SMS. However, I will be travelling overseas soon, and getting a new SIM card and number. How can I keep my accounts secure while travelling and not need to receive text messages?


We frequently advise the use of two-factor authentication to protect accounts. Two-factor is certainly better than a single unchanging password, but there's one major limitation: if you're being sent an SMS with a one-time password but you want to access that service on the same phone, your protection level has essentially evaporated. According to AusCERT, that's already a big enough issue to make two-factor systems based on sending text messages all but useless.
