Well designed, clean UI.
Functionally - works very well.

This thing is awesome! I've been using Lastpass for years and now they are getting greedy so I changed to Bitwarden, and I wish I had done this years ago. The interface is awesome and the security is second to none!

Works much better than lastpass!!.
Easier to use and no bugs bothering arround!!

The add-on works very well, I haven't had any problems with the autofill. On top of that, it's quite customizable: if you want high security, you can let the vault time out automatically (so you have to re-enter your master password) or you can go the convenient route and opt not to have to retype your password on every browser restart (or after some time). Amazing!

Works every bit as well as LassPass. Works slightly differently, but just as good so far. I used to use LassPass to sync between my phone and computer. They have recently changed their policy of their free version to only sync to a single device. Since I needed to sync to both, I found Bitwarden. After playing with it a bit, I decided to purchase the premium version. It is less that 1/2 the price of LassPass. The biggest "issue" to me is that it doesn't automatically fill in the login in pages. you have to click on the Bitwarden Icon and then click on the login you wish to use (assuming you have more than one login for a particular site). This is by design and actually, once you are used to it, it works great. I also like the desktop app for windows. Nicer than having to log into a website to perform more in depth changes/reviews of your data.

Having just migrated over from LastPass following their announcement about starting to charge for multi-device usage, I can't believe LastPass have done done me such a huge favour! Bitwarden is far superior, I'm a fan of open source software anyway and this password manager is superb. Thank you LastPass!!
