Biggest security issue you ever found or fixed?

oh that's a good one!

.

Nice

People had an Excel file storing every password to every account on every platform, for the whole company...

Including root access to all servers, and also emails.

All in plain text, of course...

A client...

Just trying to solve my biggest security issue ever..... Cutting the ties to Google I build up by myself by linking every shit to the Gmail account of mine, allowing access to all my data.
Over the years using Google and its growing services I didn't realize what a fucking monster this became and now knows almost everything if not even more about myself.

Any suggestions for good, reliable, encrypted alternative which is not reading my mails, your keyboard input, calender, everything else...... because it should be technically impossible?

I mean how to use your android phone without exposing all your data to them.
