1Password: Password Managers
1Password offers a free 30-day trial, but after that it charges a (comparatively) hefty $5 a month for what it calls 1Password Families. You get both desktop and mobile apps, free upgrades, web access, and sharing for up to five people.
Somewhat confusingly, the only other paid option is 1Password, a standalone desktop license for one person ($64.99). It includes only basic mobile apps. If you want pro features, you buy them through an in-app purchase.
You can install 1Password as a browser extension for handy access to your passwords and other info, such as credit card numbers. 1Password can also generate passwords for you.
If you using 1Password (not the Families version), you can store your data offline or sync it via Dropbox, your Wi-Fi network, or iCloud—the password manager does not provide its own sync service. You can easily export your data from 1Password so you can access it in other applications.
1Password works with OS X and Windows although, in the case of 1Password Families, the Windows version is a beta only. It also offers Android and iOS apps and extensions for most popular browsers.
