ManageEngine Password Manager Pro de ManageEngine

To make password management and auto logon activities seamless, ManageEngine PasswordManagerPro (PMP) provides the option to securely synchronize passwords across browsers through native browser extensions. The extension helps you to auto-fill passwords to websites and web applications and also launch RDP and SSH sessions. In addition, the extension allows you to view all passwords, resource groups, favorites, recently used and a search option.

Once you deploy the extension, you will be able to perform most of the password management operations directly from the browser extension, while PMP will be running in the background.

This add-on is completely free for the users. The web service Password Manager Pro, upon which this add-on is based, is available both as a free version and a paid subscription. Typically, once the trial period for the service ends, users can continue using the free version or subscribe to a paid edition. Either way, there is no separate payment required for the add-on.
