AgileBits 1Password was originally designed for the Mac way back in 2006. But today it also offers apps for Windows, Android, and iOS as well as extensions for all major browsers. It boasts some of the same features as top-tier managers LastPass and Dashlane, but lacks some key ones and overall feels a lot less polished.
1Password has a unique setup process. After entering your name, 1Password generates a 34-character “secret key.” Next you create your master password. Together, these two pieces create the full-encryption key used to encrypt your passwords and other data and you’ll need to enter them both each time you add a new device or browser extension. Given their importance, 1Password next offers to create an Emergency Kit that contains your secret key and a space to write in your master password. It saves it as a PDF, and you’re advised to store it on a USB key or in a safe deposit box.
