I've been using Norton's Identity Vault but I'm tempted to try LastPass... just seeking preference opinions from forum... If there is another option preferred, please note...
I'm using LastPass here on Chrome (the no binary version), I haven't used any other password managers.
I sometimes disable the extension since I've set-up CCleaner to keep certain cookies, and have Chrome set to block 3rd party cookies. So I'm logged in to most of the sites I visit, hence I don't need LastPass running 24/7.
I currently use Lastpass as well and works quite fine. Never really tried Norton's Identity Vault so I can't tell you what's it's like but Lastpass is one of the best free password managers out there.
If your looking for extra key security $12 yearly premium gets you grid multifactor authentication. Included the link if you were interested.
