I came here to say this. Works in browsers, phones, everywhere. Can create complex passwords for you. Data is (supposedly) encrypted by you, but stored on their servers so if you forget your master pwd, you have to reset your data. I've been using it for a few years now and I love it.
Agreed, if you're into self hosting, then vault warden is awesome. All the premium features of bitwarden for free (well if you ignore the hosting costs).
