Used for years, have 137 current passwords so NEED a program like KEY and never had a problem. SYNC feature is great as I only need to make a change on the device I am using and I know that all my other devices will update automatically. I particularly like the feature allowing you to see a history of passwords when any have been changed. I don't know any other software which offers this.
Password Manager by F-Secure is a browser extension that automatically fills in login fields with passwords from the password vault
It requires the password manager desktop app by F-Secure to be installed for full functionality
