This is a hot topic! A lot of people is thinking about how to solve this problem. We have too many passwords to remember, isn’t it? Well, this is an easy, free as in freedom and as in beer solution.
Use Firefox Sync
I used Firefox Sync a long time ago and I didn’t liked it. It was too difficult to configure another device so I switched to Chrome.
I need to sync passwords and bookmarks and Chrome was a really comfortable choice.
But now Mozilla has accounts, and Firefox 31 is out. So just login with your Firefox account and use Sync to .. emh, sync your passwords.
