Not too long ago, I decided to switch to Google Drive and Docs to write my cover letter and resumes, I already use the e-mail address to send them anyways, so using Drive and Docs seemed like a good idea.
I uploaded a template document that contains the basic information that is common on every application I send out (name, phone, Github url, previous work and education history, etc), and I made sure that only I could view the document.
I use KeePass to create and store a 64 character password (mixed with numbers, letters, and symbols), and I make it a habit to change the password periodically.
Yesterday, when I signed in, I realized the template was shared with someone that I don't even know. I can't understand how this happened, and I nearly shutdown the account. So far, I've removed the documents and migrated back to my previous workflow of using a word processor and a portable HD to store my documents.
If I were to shutdown the account, would who ever I shared the document with still have access to it? What should I do to prevent this from happening again? The information isn't too sensitive (you can get the same information on Linkedin), but I'm unsure of how to proceed.
