“Zero knowledge” means that your data is inaccessible by the password manager developer, even if said data resides on their cloud servers. When choosing a password manager, documentation should list this feature. The monitoring process scans these websites for anything related to end-users, like email addresses, passwords, credit card numbers, and so on.
That doesn’t mean these activities are instantly nefarious, but stolen user credentials are typically broadcasted, sold, and purchased on the dark web. Examples would be tax forms, scanned personal ID cards (like your driver’s license), a Social Security card, a passport, and so on. Second, premium services typically provide general online storage to back up sensitive documents and send them as encrypted attachments. Regardless, uploading and downloading data is required for multidevice synchronization, whether it’s local or in the cloud. Developers don’t have access to this data-it’s just an encrypted blob that’s uploaded and downloaded as needed.Īs shown above, Sticky Password has a Wi-Fi option, while Bitwarden has a tool to create a local service. First, data is synchronized across devices using cloud storage. There are two aspects to this feature to consider. If a password manager advertises device synchronization (most do), that data should reside on the developer’s cloud servers as an inaccessible encrypted blob.įor a more in-depth look at the essential features to consider in a password manager, jump ahead to our expanded section below. That means its developer doesn’t have access to your data. Be sure to pick a password manager that is in active development and offers end-to-end encryption, if possible.įinally, a password manager should list “zero knowledge” somewhere on its product page. You also want a password manager that supports multiple platforms, including Windows, macOS, Android, and iOS. It’s essential for day-to-day use across all accounts because passwords are often reused, too short, and easily guessed. Overall, the best password manager should generate long unique passwords that are nearly impossible to crack. They all store your login credentials, require a master password, generate new passwords, and provide an autofill function, so you’re not typing in wildly long strings of letters, numbers, and characters. The problem with shopping for the best password manager is that they’re not much different from each other.
