1Password is a commercial password manager developed by AgileBits. It stores login credentials, credit card details, software licenses, secure notes, and other sensitive information in encrypted vaults protected by a master password and a Secret Key. The service is available on macOS, Windows, Linux, iOS, Android, and as browser extensions, with data syncing across devices through 1Password's cloud. Features include a built-in password generator, secure sharing of vaults between users, and Watchtower, which flags weak, reused, or compromised passwords. 1Password offers plans for individuals, families, and businesses, with shared vaults, role-based access controls, and admin tools for team management. It uses a zero-knowledge architecture with end-to-end AES-256 encryption, meaning data is encrypted on the user's device and 1Password cannot access the contents of stored vaults. Pricing follows a subscription model with monthly or annual billing; no free tier is available, though a trial period is offered.

Google Authenticator is a free mobile app developed by Google that provides two-factor authentication (2FA) to enhance account security. It generates time-based, one-time passcodes (TOTP) or counter-based codes (HOTP) that users enter along with their password when signing into supported services. By scanning a QR code or entering a setup key, users can link the app to their accounts, ensuring that even if a password is stolen, unauthorized access is far less likely without the corresponding code from the app. It works offline, making it both secure and convenient for protecting online accounts.
