Regardless, I'm glad they are being open about this. I use 1password, so I want to know absolutely anything that could be a threat, especially after the debacle with LastPass.
1password user data is encrypted, right? so even if a hack had allowed a bad actor access to user pw databases, it's not like they would've just scored everyone's passwords.. right?
Exactly. Accounts are locked with both password and encryption key. The latter is not known by 1Password.
To be accurate, they don't know either. A login key and a decryption key are derived from password and secret key client-side.
I'm not sure about 1password, but with Lastpass, the passwords were encrypted, but not the URLs for each site. Whoever has the lastpass vault knows what sites were associated with each account, and can start targeting accounts which look valuable.
Also, and I don't mean to scare the people who use 1password, they (LastPass) lied about the extent of the encryption. Many technical details they either omitted or lied about until they HAD to reveal the true extent of the hacks that had occurred. I know, I was a LP user unfortunately. Now comfortable at Bitwarden, but 1password was an option I considered.
If they have vaults downloaded, then they can rapidly brute force the vault passwords and would like be able to decrypt a lot of them.
1password protects against this by combining the password you choose with a cryptographically random 128bit “secret key”. That one isn’t getting brute forced easily.

They document their vault security highly and it’s worth reading through.
Good point. It’s been such a long time since I’ve had to use the secret that I forgot it existed.
It’s not as simple as brute forcing the password, it’s also encrypted using a secret key. You essentially have 2 factor encryption on the vaults.
If a user was social engineered, not very tech savy to catch on to it and revealed the master password, you'd only need to guess the encryption key, no?
Yes, but the encryption key is very likely more secure than the users password to begin with.
Unless they had the encryption key.
but the encryption keys are not stored on the 1password cloud systems
