Self-Host Your Own Password Manager with Bitwarden

Today’s article delves into Bitwarden, a powerful open-source password manager that gives you complete control by allowing self-hosting on your own server.

What is Bitwarden?

Bitwarden is a robust, open-source password manager designed for individuals, teams, and businesses that prioritize data privacy and security. By self-hosting Bitwarden on your own infrastructure, you maintain full control over your credentials and ensure sensitive information stays within your environment.

Vault Health Reports – Security audit tools include checks for weak passwords, reused passwords, exposed credentials, and inactive 2FA—especially useful for teams.

Secure Sharing – Easily share login credentials, notes, cards, and identities with teams through Organizations. Control access with shared Collections and user roles.
