After getting my Keepass hacked/stolen and someone trying to purchase Ipads on my dime, I got this - after changing emails addresses and passwords.  I feel so much better using this.  Very easy to set up following instructions that can be found on the web and the apps that are necessary to use with Keepass.  I haven't set it up to use with Amazon yet.  From what I understand, Keepass is one of if not THE most stolen password manager.  That makes this little gizmo absolutely necessary.  Shout out to Cap One for taking care of the bogus charges.
Paypal did NOT help.  They said they couldn't because the charges were unauthorized.  Really?!?!?  That's why I use Paypal - for protection from this happening.
