LastPass is an award-winning password manager that saves your passwords and gives you secure access to them from every computer and mobile device. With LastPass, you only remember one password - your LastPass master password. LastPass will fill your logins for you and sync your passwords everywhere you need them.

Key Features:

• Sync all of your passwords and logins across all of your computers and devices
• Save and autofill usernames and passwords for all of your online accounts
• Use form fill profiles to streamline online shopping
• Create secure notes to store your memberships, credit cards, & other sensitive data
• Search for usernames and sites from your vault
• Organize sites by folders
• Enable multifactor authentication to lock down your LastPass account

Premium Features Include:

• Unlimited mobile access from all smartphones and tablets
• Shared family folder, to share a folder of logins & notes with friends and family
• Additional multifactor authentication options
• Offline access to your data via the mobile apps (must login at least once to store the data)

Benefits of using a password manager:

• Never forget another password
• Generate strong passwords that you don't have to remember
• Passwords are autofilled for you as you go to your sites - less typing!
• Securely share your passwords with friends and family
• Only worry about one master password

After having trialled several password managers (1Password, Locko, Dashlane, KeepassX and Lastpass), Lastpass provides by far the best experience and the most features across multiple OSes (I use OS X, iOS, Android and occasionally Windows and Linux) and devices in my opinion.

Dashlane got excluded early on for its poor browser support. Nicely designed website though!

Keepass(X) was incredibly clunky across different OSes. Not for me.

Locko was still too new to have a robust featureset and cross-device support, but had a great UI for OS X and good pricing.

1Password (1P) is obviously popular among OS X users, and I think Agilebits seem responsive and helpful developers. The problems for 1P for me were the very poor authentication options compared to Lastpass (which has extensive multifactor, one-time use, grid and other authenication options), very basic browser integration and an IMO really excessive pricing scheme (across devices and updates).

Lastpass is obviously less polished UI-wise than the native mamagers like Locko and 1P on OS X. but its browser integration is far superior and that is really where I use 98% of my passwords (as I suspect many others). I love options like grid authentication, one-time passwords and other great lastpass features. And the pricing is *much* more reasonable than most of the other options (especially 1P) considering the better functionality for my needs. As a premium user, I've always had prompt responses to my service requests.

Lastpass are starting to build (in beta) a cloud storage option outside the US to alleviate some of the US cloud-based concerns, although do remember that all data is a heavily encrypted blob, and data privacy is a global not local issue.
