Security is not just a feature. It’s our foundation.

Every design decision in 1Password begins with the safety and privacy of your data in mind.

The information you store in 1Password is encrypted, and only you hold the keys to decrypt it. 1Password is designed to protect you from breaches and other threats, and we work with other security experts to make sure our code is rock solid. We can’t see your 1Password data, so we can’t use it, share it, or sell it.

Only you have access to your 1Password data.

Your 1Password data is end-to-end encrypted to keep it safe at rest and in transit. Our security recipe starts with AES 256-bit encryption, and we use multiple techniques to make sure only you have access to your information.

Your Account Password protects your data on your devices.

1Password security begins with encryption, and we’ve taken additional steps to limit your exposure to threats outside of 1Password.


Alerts you to security breaches

Watchtower alerts you about password breaches and other security problems with your 1Password items.


Protects you from phishing

You can fool a human, but you can’t fool 1Password. It only fills your account details on the sites where you saved them.

Verified browsers

Only works in verified browsers

1Password only fills your details after it verifies that your browser has been signed by an identified developer.


Removes secrets from your clipboard

To prevent people or clipboard tools from learning your secrets, 1Password regularly removes item details from the clipboard.


Intelligent autofill

1Password securely fills credentials directly into websites, so you don’t have to type or paste your password.


Always requires your input

To protect your data from shoulder surfers and browser-based attacks, 1Password only displays or fills data when you tell it to.
