In addition to being a password manager, 1Password can act as an authentication app like Google Authenticator, and for added security it creates a secret key to the encryption key it uses, meaning no one can decrypt your passwords without that key. The plans vary, with an individual plan at $3 per month, family plan at $5 per month, the Teams starter pack (with up to 10 users a month) at $20 per month, and business at $8 per month per user. But unlike others, 1Password password manager includes additional security features like a Secret Key for additional protection and a more secure travel mode.
