Besides Passbolt we are also currently testing Bitwarden as a password manager for the company. Bitwarden comes with a bit more handy features, such as browser integration and apps for mobile devices. It also has a more convenient user interface.
However, its security features are not as good as Passbolt’s, since you can simply log in with your master password - whereas with Passbolt you need your private key, the passphrase to the private key and to be able to connect to your account from a new machine at all, you would also need access to your email account.
Bitwarden can be reached here: https://bitwarden.inspiredminds.at/. You should receive an invite to your email account with instructions on how to set up an account of your own.
