Keeping Dropbox secure is at the heart of what we do, and we’re taking steps to improve the safety of your Dropbox even if your password is stolen, including:
•Two-factor authentication, a way to optionally require two proofs of identity (such as your password and a temporary code sent to your phone) when signing in. (Coming in a few weeks) •New automated mechanisms to help identify suspicious activity. We’ll continue to add more of these over time. •A new page that lets you examine all active logins to your account. •In some cases, we may require you to change your password. (For example, if it’s commonly used or hasn’t been changed in a long time) At the same time, we strongly recommend you improve your online safety by setting a unique password for each website you use.
