Make Your Drive More Secure
Fortunately, many of the aforementioned issues can be resolved with good profile management practices. The simplest thing you can do is enable two-factor authentication. Use the Google Auth app, or an NFC security token to make it harder to break in.
You should also be prepared for extreme cases - such as losing your phone or token. Either should be password-locked (or pattern-locked, in the phone’s case) and a plan should be in place. It’s a good idea to log in on your computer and use the Google account settings to log your phone off.
If your PC or Mac aren’t close by, and you fear you won’t make it in time, then you should have your Google Security Codes on hand. Write this massive password down in advance, and keep it safe. It will let you log in from anywhere, even if your Auth app is inaccessible, or your password has been changed.
Is Google Drive secure for business? When you really need to share files and documents, but don’t want any of it to leak, then permission management is the thing for you. Adjusting permissions individually for docs, files, and folders can prevent viewing and copying by third parties.
To make things even safer, more encryption can be added to files and folders using third-party apps. Even if your drive is fully compromised, these files will be impossible to open and view, unless the attacker can decrypt them.
