Password Safe has an assignable global hotkey system, but it falls a little short of its counterpart in KeePass and 1Password. With those programs, a single master hotkey activates those programs and performs autotype for a password for the current domain. With Password Safe, you can define a global hotkey to bring up the main program menu (it's not assigned by default), but from there you have to select the appropriate entry and perform autotype yourself.
It's a minor drawback, but it becomes annoying after a while. To use autotype reliably with this feature, you need to store the log-in URL with the username/password entry, and not just the general domain name as you can with KeePass.
Cost: Free open source. Platforms: Windows, Linux, Java.
Password Safe is reminiscent of KeePass, but doesn't integrate as tightly with the rest of your system as KeePass does.
RoboFormRoboForm has been around since 1999, growing from a general Web-form-filling program to a full-blown password and credential manager. It stores not just log-ins, but also browser bookmarks, user identities, personal contacts, and sundry notes and comments. It's broadly useful outside of just browser log-ins.
RoboForm comes with plug-ins for close integration with most common Web browsers -- Firefox, Chrome, Opera, and IE -- which you have the option to install when you first set up the program. You can always change which plug-ins you use, should you happen to switch browsers later.
Once set up, browsers that use RoboForm integration sport a toolbar. Passwords and other form information you submit to a website are automatically captured by RoboForm and saved into the program's database. You can also add arbitrary fields to each record, such as another password field or a comments line. RoboForm integrates with regular Windows applications, not just Web browsers, but if you're leery of doing that, you can always resort to copy and paste to get data out of RoboForm.
To use the captured form information -- for instance, to log into a given site -- you either click the appropriate button on the toolbar or use a keystroke combination to perform an autofill action. I wasn't crazy about the look of the toolbar, and the in-browser hotkeys for RoboForm work even without it. Thus, I hid it without disabling it and was none the worse for the action.
