The fact it’s open source also means it’s free to use and it will behave just like LastPass’s free tier, allowing you to use unlimited devices and access your passwords and other data from any of your devices. We think the best choice is Bitwarden because it’s open source, so anyone can inspect its code, and this makes it trustworthy. But while this new restriction may be ok for some people, for most it’s a dealbreaker and they’ll be looking for an alternative free password manager. This decision is designed to persuade people to upgrade to LastPass Premium. So if you login on your phone, that’s it: you can only use LastPass on phones and tablets, but not Windows laptops and PCs. After 16 March 2021, whichever device you use LastPass on first will become your choice. LastPass is changing its free tier so that users can pick between computers (laptops, PCs) and mobile devices (phones, tablets).
