Bitwarden Tutorial: The Best Open-Source Password Manager
Bitwarden: Stop Using the Same Password for Every Website
Solves in one sentence: Can’t remember dozens of website account passwords? Bitwarden securely remembers all your passwords, with just one master password needed.
“Your password has been leaked, please change it immediately” — do you panic when you get this notification?
Most people use their own “universal password” system: core password + website name variation. Either you can’t remember them, or their security is questionable.
A password manager solves this problem. And Bitwarden is the most recommended of all password managers.
What Is Bitwarden?
Bitwarden is an open-source password manager. It encrypts and stores all your account passwords in a single “vault.” You only need to remember one master password to access all your passwords. The password vault is end-to-end encrypted — even Bitwarden itself can’t see your passwords.
The problem it solves: Lets you use a unique, strong password for every website, while only needing to remember one.
