LastPass (shown here) keeps track of your user IDs, passwords, and other settings; stores them in the cloud; and offers them to you with a click. LastPass does its AES-256 encrypting and decrypting on your PC, using a master password that you have to remember. The data that gets stored in the cloud is encrypted, and without the key, the stored passwords can't be broken, unless you know somebody who can crack AES-256 encryption.
LastPass works as a browser add-on for Edge, IE, Firefox, or Chrome, so all your passwords are stored in one place, accessible to any PC you happen to be using — if you have the master password.
LastPass is free for personal use on PCs. The Premium version, which works on all sorts of mobile devices, costs $12 per year.
