1Password vs Auth0

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.

Auth0 is a customer identity and access management (CIAM) platform that developers use to add login, sign-up and authorization to their applications. Founded in 2013, it was acquired by Okta in 2021 and now operates as Okta's customer identity product, alongside Okta's workforce identity business. Its job is to handle authentication so product teams do not build password storage, MFA and SSO themselves.

The platform centers on Universal Login, a hosted login page that supports social providers, enterprise connections (SAML, OIDC, Active Directory), passwordless email and SMS, passkeys and multi-factor authentication. Organizations support B2B multi-tenancy where each customer brings its own identity provider, Actions let teams run custom code in login and registration flows, and Fine-Grained Authorization handles relationship-based permissions. Attack protection covers bot detection, breached password checks and brute-force limits. The free plan was expanded in 2024 to 25,000 monthly active users; paid tiers are priced by MAU and features, and enterprise connections push buyers into higher plans quickly.

Auth0 fits B2B SaaS companies selling to enterprises that demand SSO, and consumer apps with large user bases and compliance requirements. It is less attractive for small teams that want drop-in UI components and predictable pricing: Clerk is simpler for React and Next.js apps, while Keycloak and Better Auth give full ownership without per-user fees.
