Even if 1Password gets hacked and your sensitive data stolen, there is practically no chance that cybercriminals could decrypt it. Three things are needed to decrypt your data: your account password, your Secret Key, and the encrypted data itself. You’re the only one who knows your account password, your Secret Key is generated locally during setup, and all your data is encrypted/decrypted on your device. So, even if a cybercriminal mastermind would somehow manage to steal your account password, they wouldn’t be able to get inside your vaults and grab what’s in it.
