1Password is a password manager made by 1Password, a company based in Toronto, Canada. A password manager stores login credentials in encrypted vaults and fills them in on websites and apps, so that each account can have a unique, strong password that nobody needs to remember.
Apps run on macOS, Windows, Linux, iOS, Android and Apple Watch, with browser extensions for Chrome, Safari, Edge, Firefox and Brave. 1Password generates passwords, saves and autofills logins, two-factor authentication codes, payment cards and addresses, and supports passkeys. Vaults are shared with family or team members, and expiring links share an item with people who do not use 1Password. Watchtower flags compromised and weak passwords. All data is protected with end-to-end AES 256-bit encryption, and the key is derived from the account password together with a Secret Key. Business plans add role-based permissions, sign-in through identity providers such as Okta and Entra ID, and developer tools such as a CLI and SSH key signing; larger companies can buy access management products for people, AI agents and machines.
1Password is a subscription service, billed monthly or yearly, with a 14-day free trial.
