Encryptr is a secure and easy to use password manager. By design it opts to be simple rather than full featured, to make it easier to audit the code and keep the bugs out. That means no browser integration, no tagging or sorting or classification of entries, no plethora of different kinds of entries, no web access, and no known security vulnerabilities. I’m happy to sacrifice a kitchen sink full of features in exchange for that last point. It is open source and available at no cost.
To obtain Encryptr, download it from the maker’s website. It is available for Windows, Mac, Linux, Android, and iOS. For Linux users, DEBs and RPMs are available but repositories are not. Once downloaded, install it in the usual way for your operating system.
