Authgear

Authgear is an identity-as-a-service platform for authentication and user management in web and mobile applications. It supports sign-in with email, phone, usernames, passwords, one-time codes and magic links, plus mobile biometrics, passkeys and multi-factor authentication through SMS, email or TOTP apps. Google, Apple and Azure Active Directory are among its identity-provider options. Authgear provides single sign-on across web and mobile apps, including SAML SSO for web applications. Its user-management portal supports profile management, password resets, account locking, and scheduled deletion or anonymization. Developers can use official SDKs for React, React Native, Ionic, Android, iOS and Flutter, alongside OAuth 2.0/OpenID Connect, administration, import and export APIs. The service is open source and offers self-hosting; its hosted service is in the USA on Google Cloud Platform infrastructure. The Free plan includes two applications, two admin seats, one-day log retention and community support. Paid plans start at $50/mo.

Authgear covers sign-in, identity management and SSO for web and mobile applications, with SDKs and APIs for integration. Its free plan has defined application, admin-seat and log-retention limits; paid plans start at $50/mo.

Authgear suits teams building web or mobile apps that need authentication, identity management or SSO. Self-hosting and SDK options may also suit developers who want to integrate or operate the service themselves.

Overview

Authgear is an identity platform for teams building web and mobile apps that need control over sign-in and account management. It is best suited to developers who want multiple authentication methods, SSO and the option to self-host. Its breadth is appealing, but the lower plans limit applications, admin seats and log retention.

Authgear describes its software as open source and says teams can self-host, migrate or move to any OIDC-compliant provider. Its hosted service runs in the USA on physical infrastructure using Google Cloud Platform data centers. Authgear states that it is ISO 27001 and SOC 2 Type II compliant.

A 30-day money-back guarantee applies to any SaaS plan.

Key features

Authentication and account access

Sign-in options include email, phone, username and password, alongside one-time passcodes and magic links. Google, Apple and Azure Active Directory are among the supported identity providers. Passkeys and mobile biometric login add passwordless choices, while multi-factor authentication can use SMS, email verification or TOTP authenticator apps. This range suits products serving different user preferences, but teams using SMS or WhatsApp should account for metered usage on paid plans.

SSO spans multiple web and mobile applications, with SAML SSO for web apps. That makes Authgear relevant to teams that need shared sign-in across their own apps as well as workforce authentication.

User administration and integration

The management portal supports password resets, account locking, profile management, and scheduled account deletion or anonymization. Those controls help teams manage the account lifecycle without treating sign-in as the only identity task.

Official SDKs cover React, React Native, Ionic, native Android, iOS and Flutter. OAuth 2.0/OpenID Connect, Admin, User Import and User Export APIs provide additional integration paths. Listed integrations include Google Workspace, Microsoft 365, Salesforce, Slack, Mailchimp, Mailgun, Postmark, SendGrid, Telegram, WhatsApp and Zapier.

Pricing

The free plan costs $0 per month and includes unlimited MAUs, 100 SMS/WhatsApp messages, two applications, two admin seats, one day of log retention and community support. The unlimited MAUs are generous for a free tier, but the message allowance and short retention window may constrain teams relying on messaging or needing a longer operational record.

Developers costs $50 per month. It keeps unlimited MAUs, two applications, two admin seats and one day of log retention, while SMS/WhatsApp becomes metered and support upgrades to priority email. This is a modest step up from Free: it suits a small deployment that values faster support, but it does not add app capacity or retention.

Business costs $500 per month and includes 25,000 MAUs, with an additional $50 per 5,000 MAUs, metered SMS/WhatsApp, five applications, five admin seats, 60 days of log retention and a dedicated Slack channel. The higher price is most defensible for teams needing more app and admin capacity plus substantially longer retention; smaller projects may find the jump from Developers hard to justify.

Enterprise uses custom pricing and adds volume discounts, data residency, a custom SMS gateway, a tailored SLA and a dedicated account manager. It is the plan for organizations with deployment or service requirements beyond the fixed tiers. All SaaS plans carry the 30-day money-back guarantee.

Platforms

Authgear supports Android, iOS, web and API deployments, as well as self-hosting. The platform breadth and mobile SDKs make it a practical fit for teams serving both browser and app users; self-hosting is useful for organizations that want to run the software themselves.

Who it's for

Authgear is a strong candidate for development teams building multiple web or mobile applications that need flexible authentication, account administration and SSO in one identity platform. It is less compelling for a small team that needs extensive log retention or more than two apps and admin seats but does not need Business-tier capabilities.

Pros and cons

• Pros: Broad sign-in coverage, including passkeys, biometrics, OTP and magic links, gives teams options for different user journeys.
• Pros: SSO, SAML support and user-lifecycle controls extend the product beyond basic login.
• Pros: Open-source positioning, self-hosting and OIDC portability offer an exit path from the hosted service.
• Cons: Free and Developers both stop at two applications and two admin seats, limiting growth without moving to the $500-per-month Business plan.
• Cons: One-day log retention on the first two tiers is brief; 60 days requires Business.
• Cons: SMS/WhatsApp messages are capped at 100 on Free and metered on paid tiers, so messaging usage affects plan economics.

Alternatives

• cidaas is worth comparing if its free customer IAM trial or support for Windows matters to your deployment.
• miniOrange Identity and Access Management is an alternative if you need its broader platform coverage, including Linux, macOS and Windows, or a free tier centered on customer identity and social logins.
• Descope may suit teams prioritizing open-source SDKs and a free tier with published MAU, tenant and SSO-connection allowances.
• Frontegg is an option for teams whose needs align with its free allowance of 7,500 monthly active users, five enterprise connections and unlimited organizations.
• FusionAuth is worth considering if a self-hosted free community plan and broader desktop platform support are priorities.
• Google Cloud Identity is another identity option.
• Hanko may appeal to teams looking for a free starter tier with 10,000 monthly active users and two projects, or a $29-per-month Pro plan.
• Okta Customer Identity Cloud is another customer identity platform to compare.

Verdict

Choose Authgear if you need flexible authentication, SSO and user management for web and mobile apps, with self-hosting or OIDC portability as meaningful safeguards. Its main drawback is the sharp tier split: two apps, two admin seats and one day of retention persist through the $50 Developers plan, while meaningful capacity gains begin at $500 per month. Teams that can work within those limits get a capable identity toolkit; teams that cannot should compare alternatives before committing.
