![]() Privacy: A password manager shouldn’t share data with third parties for advertising, so we check both the privacy policies and the mobile apps to confirm that they aren’t sharing data they aren’t supposed to.Security audits aren’t perfect-they offer just a snapshot of the software and infrastructure-but they are a signal of trust and transparency. But those promises of security only go so far, so we require that any password managers we recommend participate in regular third-party security audits (preferably audits that they make public) and have a bug-bounty program. A good password manager needs to use strong encryption to protect your data on your computer, on your password manager’s server, and when your data is moving between the two. Good protection for your passwords: You’re trusting your password manager with your entire digital existence, and your password manager should store your data securely.Regardless of the password manager you use, it’s important to protect your data with a strong master password-we have advice for how to do that below. Bitwarden works on the same devices as 1Password, so you can use it with any computer, phone, tablet, or browser. But the free version of Bitwarden offers the core features you need in a password manager, including the ability to sync as many passwords as you want across as many devices as you own, support for software two-factor authentication, and sharing between two people with separate logins using a two-person organization. Plus, Bitwarden isn’t as polished overall and lacks the in-app guidance of 1Password, which makes it harder for beginners to get the hang of. I'm using Bitwarden because I don't like the way 1Password looks.The free version of Bitwarden gets the basics right and doesn’t cost a thing, but it lacks a few features that make 1Password such a standout option, such as password checkups and 1 GB of encrypted storage (all features you can find in Bitwarden’s reasonably priced, $10-per-year premium plan). I like the fact that Remembear (like the much much better known 1Password) uses a locally-stored secret key to restrict access to properly authenticated devices. It does NOT draw info from the device (like machine ID or whatever) because once I set up an account on one of my computers, I can immediately get the TOTP on my phone or another computer. (I've done this using Bitwarden and Remembear.) I assume that the algorithm that generates the TOTP using input from some other detail, presumably the login name/email and/or the passphrase. You can set up two (and presumably more than two) password managers and/or authenticators to provide the TOTP for the same account. Hen you scan a qr code with Google Authenticator or Bitwarden app (or manually enter sync code on BW browser extension), the app and the website are sharing a secret.Īpparently it is not a completely secret secret. The secret is of course encrypted just like the passwords, so if data is leaked from BW's servers, the encryption would protect password and totp secrets (assuming BW didn't mess anything else up). When you log in and enter the authenticator code, website will check if what you entered matches what it generated.īitwarden and Google authenticator works exactly the same way, except that, in Bitwarden's case, the shared secret is stored in your vault on BW's server along with the password for the website. ![]() Then, both the authenticator app (or BW browser extension) and website uses the shared secret and Unix time to generate otp every x number of seconds. In short, when you scan a qr code with Google Authenticator or Bitwarden app (or manually enter sync code on BW browser extension), the app and the website are sharing a secret. Technical explanation starts at 6:30 mark. Here is a computerphile video on one time passwords, including TOTP.
