One of the first rule you must follow - do not use any of common password managers.

This things can be biggest secure hole making huge damage.

It's not 100% bullet proof, but I realized I myself has become the biggest risk on my passwords all over sites. Most of techie people I know have recommended the tool.

Most of the people are quite stupid, like recommending cloud services for private storage and backup :-)

Please understand - it is enough to make proper malware and add it to one of the packages selling in the dark parts of the Internet and you will instantly provide ALL of your passwords to all sites.

What to use - get any $30 Android smartphone, install it in to crandle, do not install SIM and turn off all wireless connections, install any simple local password manager (without any integration with anything).

All that you risk here is the keyboard hooks / screenshots via malware, but it will be only sites you visited and they will also work with your password manager (if they know about it), just will get all the stored passwords at once.

Managers working via Bluetooth and USB keys are also risky as they have temporary access to whole database.

I'd had done it if I didn't need to "support" wifey.

What you mean?
