Bitwarden

Open Source

Self-hosted

E2EE

Bitwarden is a free and open-source secure password management software that stores sensitive information such as website credentials in an encrypted vault. You can either use Bitwarden Cloud's free plan or you can self host it for boosted security.

Notes:
Bitwarden is, in our opinion the simplest way to store passwords online. As mentioned, Bitwarden is open source, and you can host your own Bitwarden Instance, making it decentralized.

If you're looking for an offline password manager that does not need to utilize the internet, we suggest giving KeePassXC a go. See more about KeePassXC below.

KeePassXC

Open Source

Self-hosted

KeePassXC is a modern, secure, and open-source password manager that stores and manages your most sensitive information. You can run KeePassXC on Windows, macOS, and Linux systems.

Notes:
KeePassXC is a community fork of KeePassX. It is completely open source, feature-rich, and modern. Since KeePass runs locally on your device, it can be harder to sync your passwords across devices.

If you're looking to securely & easily store your passwords in the cloud & sync them across devices, we suggest giving Bitwarden a try.
