1Password vs Clerk

1Password is a password manager for individuals, families and businesses, made by AgileBits, a company founded in 2005 in Toronto, Canada. It is known for a strong security track record, polished apps on every major platform and a design that makes good password habits easy for non-technical people.

1Password stores passwords, passkeys, credit cards, secure notes, documents, SSH keys and software licenses in encrypted vaults that can be shared with family members or colleagues. Data is protected by end-to-end encryption that combines your account password with a locally generated Secret Key. Watchtower flags weak, reused and breached credentials and sites that support passkeys or two-factor authentication, and Travel Mode hides selected vaults when crossing borders. For businesses, plans add SSO with Okta, Microsoft Entra ID and Google Workspace, admin policies, activity reporting, provisioning and free Families accounts for employees. Developer tools include a CLI, an SSH agent, Git commit signing and Secrets Automation for infrastructure. Extended Access Management, built partly on the 2024 acquisition of Kolide, adds device trust and discovery of unmanaged apps.

1Password fits households and companies that want strong security with excellent usability. There is no free plan, only a trial. Bitwarden is the leading open-source alternative with a free tier, Proton Pass suits privacy-focused users, and Dashlane and Keeper compete in the business market.

Clerk is an authentication and user management service built for modern JavaScript applications, based in San Francisco. Instead of writing sign-in flows yourself, you drop in prebuilt React components such as SignIn, SignUp, UserButton, UserProfile and OrganizationSwitcher that look polished out of the box and handle the security details behind them.

Clerk supports email and password, magic links, one-time codes, passkeys and more than twenty social providers, along with multi-factor authentication, bot protection, session management and device tracking. Organizations, roles and permissions cover B2B SaaS needs, and SDKs exist for Next.js, React, Remix, Expo, Astro, Vue and backend frameworks. Since February 2026 the free Hobby plan covers up to 50,000 monthly retained users per app, replacing the earlier 10,000-user limit; Pro and Business are flat monthly fees with per-user charges above the included volume, and SAML SSO and advanced MFA sit in paid tiers. In 2025 Clerk Billing, built on Stripe, added subscription plans and feature gating tied to users and organizations.

Clerk fits React and Next.js teams that want production-grade auth with excellent UX on day one. The trade-offs are that user data lives with a third party, per-user costs grow with scale, and non-JavaScript stacks are less well served. Auth0 targets enterprises with broader protocol support, Supabase Auth and Firebase Auth come bundled with a backend, and Better Auth or Keycloak let you own the data entirely.
