Proton Pass is a password manager from Proton, the Switzerland-based company famous for its secure email service Proton Mail and other products. In a very short time, the product has grown into a simple but powerful program that can compete with any of the entries in our best password managers roundup. The price is also right, especially when bundled with other Proton products. That said, there are some issues with daily use you may want to keep in mind.
