1Password

1Password dominates the password management space with 15 million users and $250M ARR in 2025, outpacing #2 Cloudflare WARP in consumer adoption through its end-to-end encrypted vaults, Travel Mode for border crossings, and Passkey support for the passwordless future. Its Watchtower feature actively monitors credentials against Have I Been Pwned's database of 15 billion compromised accounts, providing real-time breach alerts. This combination of security and usability makes it 30% more trusted than the average password manager, according to user retention metrics.
