1Password

1Password is a password manager and secrets management platform used by over 150,000 businesses and millions of individuals to securely store, share, and manage passwords, API keys, SSH keys, certificates, and sensitive credentials. Founded in 2005, 1Password is a preferred choice for engineering teams due to its developer-focused features: the 1Password CLI for scripting credential retrieval, SSH agent for seamless Git authentication, and Secrets Automation for injecting secrets into CI/CD pipelines without hardcoded credentials. 1Password's Team and Business vaults provide shared credential management with granular access controls: vault-level sharing, individual item sharing with expiry, guest access for contractors, and activity reports showing who accessed which credentials and when. The Travel Mode feature temporarily removes sensitive vaults from devices when crossing borders, providing protection against device inspection. 1Password Developer Tools include the 1Password CLI (`op`), a biometric-secured SSH agent for macOS/Windows, shell plugin integrations for AWS CLI, GitHub CLI, and 20+ developer tools, and Secrets Automation for programmatic credential injection into GitHub Actions, Kubernetes, and CI/CD systems.
