Any excuse for not using a password manager have been vanquished. LastPass will now let you access your password vault from multiple devices like your phone, browser, desktop for free. Prior to this change it was free to use on your desktop but to use it on your phone, tablet, Chrome extension, etc. you'd need to subscribe… though it was only $12/year (still worth it).
Premium users will still get some added benefits though, including priority customer support, group password sharing, and extra two-factor authentication options.
I've been a long time subscriber and recommend it to everyone. I know there are other options out there (Dashlane is supposed to be nice) but LastPass has been superb. They've consistently added features such as auto-changing of passwords on popular sites, the ability for LastPass to auto-login, not just to websites but even in apps, on your mobile devices, two-factor authentication, etc.
