is it worth keep all your info 1 bit of software

Hello @alistairmck! 👋

We have a blog about this topic here: TOTP for 1Password users

if 1password server was hacked

No one but you can decrypt your information. Even if 1Password was hacked the hackers would only find encrypted gibberish that means nothing without your 1Password account password and Secret Key. The difference between the services whose data breeches you may have read about in the news and 1Password is the end-to-end encryption that 1Password uses. Other services either store their information in the cloud unencrypted or encrypted using a key that they control. With 1Password all of your information is stored encrypted using your own private keys that are derived from two secrets that only you know: your 1Password account password and your Secret Key.

Let me know if you have any questions after taking a look at the blog. 🙂
