Try this: https://www.dropbox.com/try_twofactor Although tray login still logs you in without the need to enter password or the code.

That worked, thanks! Also, I just discovered a checkbox under 'Account Settings' that seems like it's an opt-in for early releases. OP probably already had this checked?

Can't find that here. Care to post a screenshot somewhere? Anyone know how to enable this? Or if it can be enabled client-side at all?

Not working for Martinique (FWI), country code 596. Still waiting for a SMS to come. Asked twice 5 and 10 minutes ago. Maybe the country list should be edited to only list countries where SMS can be sent? (I have no problem with other 2-ways services I use)

Lack of SMS shouldn't be a problem. You can use two factor authentication with the app version.It's on that same page.

Yes but SMS are handy. BTW Just got both of them with a 7 hours delay.

If you want to get the most out of this, use a hardware token generator instead of a phone or computer. Example: http://hackaday.com/2012/07/11/time-based-one-time-passwords... http://lab.infoserver.com.br/wiki/index.php/Projects:arduino...

That looks like a software generator running on Arduino.

I stand corrected. The device is more of a physical/hardware token generator than a phone or computer in that it's stand-alone. Phones with radios permanently switched off or computers without network access are probably as secure.

If Dropbox were designed to handle sequentially-numbered blobs of encrypted data, changing one file would require your other devices to download only that file (an encrypted blob of roughly the same size). With a TrueCrypt volume or other encrypted file solution on top of Dropbox, you have to resync the entire multi-GB volume any time a single file in there changes, since to Dropbox it's just one big file. (Another o…

Only part of a truecrypt volume changes when you make a change to the data within. Since Dropbox intelligently syncs files in parts, only part of a truecrypt volume has to be re-uploaded when something changes -- not the entire multi-GB file. I know because I do exactly this with a 1GB file. It takes about 2 minutes to sync when I unmount the file. Dropbox is not re-uploading all 1GB. However, like the other commente…

Very interesting, I did not know that.
