Yes, Bitwarden is very safe. It protects user passwords with 256-bit AES encryption , which makes it basically impossible for hackers to access the data on Bitwarden’s servers. Bitwarden also has a zero-knowledge policy, so not even Bitwarden staff can access your data. Bitwarden’s open-source development means that a ton of cybersecurity experts around the globe have extensively scrutinized it. Many security-minded users stand by Bitwarden as one of the most secure password managers on the market because the Bitwarden community has carefully analyzed every piece of its source code.

Bitwarden Free is one of the most full-featured free password managers on the market . Here’s what Bitwarden users get for free: Unlimited password storage on unlimited devices. Secure notes, credit cards, and identity storage. Unlimited password sharing with one user. Bitwarden Send for text notes. Data breach scanner. Password generator. 2FA compatibility with TOTP authenticators like Authy and Google Authenticator. Biometric login with iOS, Android, and Windows Hello. Bitwarden Free is pretty good, but I still recommend upgrading to a paid password manager. Bitwarden Premium is a very affordable and secure option. It offers a lot of excellent additional features, like vault auditing, USB-key 2FA compatibility, a built-in TOTP Authenticator, and 1 GB encrypted storage, all for much less than competitors.

Does Bitwarden work for Windows, Android, macOS, and iOS?

Yes! Bitwarden is compatible with all major operating systems — it has a desktop app for Windows, MacOS, and even Linux, a mobile app for Android and iOS , a web app, and browser extensions for an impressive range of browsers, including Chrome, Firefox, Opera, Edge, Vivaldi, Brave, and Tor. Bitwarden lets you save an unlimited number of passwords across all devices, operating systems, and browsers, and you can sync your data either through the cloud or through your local network.

Where are Bitwarden passwords stored?

Bitwarden offers users two locations to store their passwords. Storing passwords on Bitwarden’s servers allows for simple cloud-sync between all devices, and Bitwarden protects user passwords with 256-bit AES encryption and a secure SRP handshake. For users with strong network security, Bitwarden also offers the option for local data storage . You can keep your data within your network, which eliminates the (extremely low) risk of a man-in-the-middle attack. Bitwarden is one of the only free password managers that offer local data storage.

Does Bitwarden have an auto-fill vulnerability?

The short answer is no. Auto-fill on page load is a feature included in Bitwarden’s browser extensions that is turned off by default. Although it is typically safe, this feature is not enabled by default due to the risk of compromised or untrusted websites using it to obtain login information. Unless you deliberately change the settings to enable the ‘auto-fill on page load’ function, this is not something you need to worry about. And it comes with a visible warning, telling you that it is off because it can be potentially dangerous. Bitwarden has also taken some additional steps to ensure users’ safety by only filling iframes from trusted websites. If users manually auto-fill an untrusted iframe, Bitwarden will display an alert that will give them the option to either cancel or proceed.

Does Bitwarden support passkeys?

Yes, Bitwarden is fully passkey-compatible . It’s a great alternative to traditional passwords and can be fully integrated into your Bitwarden account.
