Open source, very effective for personal use.
It provides a very clean integration with mobile application to sync passwords across devices.
I've experienced for professional use one of the leading vendors but I switched for my personal password manager to Bitwarden and I also suggested it to my friends.

Love this app. Makes life much easier, and I feel more secure using it.

This vault is so perfect, i love it.

完美！！！

Perfect PW-Manager, usability of Firefox extension flawless. Highly recommended!
