KeePassXC (or Vaultwarden)

With the steady rise in cyberattacks, using a dedicated password manager to store, retrieve, and generate unique passwords for every service is more important than ever. Now, this is one category of software where folks tend to gravitate toward closed-source options. Most people either rely on the password manager built into their browser or turn to third-party services like 1Password, Dashlane, or NordPass.
