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.
ClipperZ is an open source project that you could host yourself on a private server only accesible via your vpn. Passwords are encrypted in the browser before being sent to the server.
I would suggest a personal encryption technique, like for example whenever you save passwords, alter some letters at specific positions personally known to you, ( e.g may be the first and second last). For example you are storing password foo762. don't save as "foo762" instead alter first and last by next digit-letter, like "goo772". trick, you must know positions and addition/subtraction by 1,2 etc, of your choice.
