1Password is an access management platform that stores passwords, passkeys, and secrets for individuals and businesses, now extended to AI agents and automated workloads.

Password vaults - Store logins, passkeys, credit cards, and notes with autofill in browsers and apps.
Enterprise password manager - Shared vaults, access reviews, and credential governance for teams.
Credential broker - Verifies AI agents and machine workloads at runtime and delivers only the credentials each is authorized to receive.
Privileged access - Just-in-time, just-enough access instead of standing privileges.
SaaS manager - Discovers AI and SaaS tools in use and tracks token and license spend.
Apps for every device - Native apps for macOS, Windows, iOS, Android, and Linux, plus browser extensions and a command-line tool.

It is used by individuals who want their logins in one place and by IT and security teams that manage access for employees, contractors, developers, and AI agents.
