Following this discussion about "Online Passwords Managers" I wonder whether it is a good idea to store the passwords using a spreadsheet inside Gmail documents? I mean, it seems to me that these password will be as safe as my Gmail account which I consider to be safe enough. Is my assumption correct, or this way of storing passwords is not recommended?
I have done that before and it is a fairly good solution when you need to share certain password lists with other administrators. Yes, your gmail account can be somewhat safe if you use it correctly. On the other hand, gmail is also a pretty big target, is susceptible to government subpoenas, and you have to be VERY careful that everything that connects to your gmail account uses a trusted SSL connection. It is very easy to take over a gmail account just by sniffing unencrypted traffic.
My preferred solution, other than an online password manager, is to place a password-protected excel spreadsheet on a shared cloud storage folder.
