1Password

1Password is a premium password manager developed by AgileBits Inc., a Canadian company founded in 2005 and headquartered in Toronto, that provides secure storage for passwords, passkeys, credit cards, software licenses, secure documents, and SSH keys through end-to-end encryption with a unique dual-key architecture combining a Master Password and a Secret Key, adopted by over one hundred fifty thousand businesses including IBM, Slack, GitLab, and Salesforce for enterprise credential management. The Secret Key architecture generates a unique thirty-four character cryptographic key on each device, combined with the user's Master Password to create the encryption key, ensuring that even if the Master Password is compromised, the encrypted vault data remains inaccessible without the Secret Key stored locally on trusted devices. The watchtower security dashboard monitors vault items against known data breaches using integration with HaveIBeenPwned, flags weak and reused passwords, identifies websites supporting two-factor authentication, and alerts about compromised or vulnerable items requiring password updates. The Travel Mode safely removes sensitive vault items from devices when crossing borders, restoring them upon return. The shared vaults and granular permissions enable team and business credential sharing with role-based access, activity logging, and administrative controls. The SSH agent integration manages developer keys for Git operations. The passkey support enables creating and storing passwordless credentials. The Developer Tools include CLI access and shell integration. The browser extensions auto-fill credentials, payment information, and identities across Chrome, Firefox, Safari, and Edge. Designed for individuals, families, development teams, and enterprises.
