This is an excellent add-on, because it works in all of my platforms, all my PCs. I can share passwords with my family (have paid for the family account and it's definitely worth it), I can use it via CLI if I need to login to my remote system and can use it to generate secure passwords with a variety of rules.
I also *love* that I can setup my own container and point my apps towards it, giving me 100% ownership of my data, however I find that unnecessary, as I am very satisfied with the online version.

Best online password manager

Works very well for me.

Great extension. Does not suffer from account recovery exploit in LastPass. Works across desktop and mobile without trouble.
