Codebook running on mobile phones and desktops

Codebook Cloud

Codebook Cloud is a sync service for the Codebook password manager, built and run by Zetetic, providing Automatic Sync and Secure Sharing.

Free to try with a subscription, starting at $5/month.

Benefits of Codebook Cloud

While Codebook supports a few different sync services, Codebook Cloud is the best way to keep your passwords and other secure data in sync across all of your devices:

Automatic Sync

No need to remember to manually sync all your devices after you edit your data in Codebook. When you create or update a password, or edit any other data, Codebook Cloud's Auto Sync feature takes care of ensuring it syncs to your other devices.

Secure Sharing

Codebook Cloud allows you to securely share passwords and other credentials with colleagues, family, and friends. Secure Sharing uses state-of-the-art ML-KEM and ML-DSA algorithms to protect your data.

Reliability

Have you ever deleted something important by accident and needed to get it back? Our support team can assist you in rolling back inadvertent changes sent to Codebook Cloud.

Available Everywhere

Away from your home or office Wi-Fi? All you need is an Internet connection. Codebook Cloud syncs over HTTPS, requiring no special firewall exceptions.

Your Eyes Only

All of the data that you store in Codebook Cloud is encrypted before it ever gets to us, with your Sync Key, which we do not have. If you decide to use Codebook Cloud, we will be unable to decrypt and read your Codebook data stored on our servers. Learn More.

Robust Security

We do not encrypt your cloud data with your Master Password. Even strong Master Passwords are rarely totally random, exposing them to advanced cracking techniques. Because your sync data is instead encrypted with your Sync Key, which is a totally random stream of bytes, this type of password cracking is not possible. Learn More.
