1Password surpassed 15 million paid users globally in Q1 2026, with 150,000 enterprise customers, making it the second-largest choice in the password management market after the open-source Bitwarden. Its core competitive edge lies not in the basic function of "storing passwords," but in three features that other mainstream tools commonly lack: Watchtower's proactive breach detection, Travel Mode border protection, and SSH/Git integration.
