LastPass remains something of a gold standard for password managers. One of the first full-featured tools of its kind, this combination vault, form-filler, and password generator ticks off all the boxes in our password manager checklist.
After you sign up and install the LastPass browser plugin, it captures your login credentials when you visit a website for the first time. When you return to a site, a small icon appears in its login fields showing how many accounts you have stored. Clicking it opens a drop-down menu revealing each account so you can select the appropriate one. You can also select an auto-login option for each account to have LastPass sign you in automatically whenever you visit that site.
