## Choose a product for your use case

- [Application sign-in](https://sudomimus.com/en-US/application-login/index.md): Add passkeys, email codes, and social sign-in to your app.
- [OpenID Connect](https://sudomimus.com/en-US/openid-connect/index.md): Connect to Sudomimus with an existing OIDC library.
- [Agents & automation](https://sudomimus.com/en-US/agents-automation/index.md): Give agents, scripts, and background jobs their own identities.
- [Enterprise SSO](https://sudomimus.com/en-US/enterprise-sso/index.md): Let organization members sign in with their company identity provider.

## Security you can trust

Passkeys and WebAuthn let users sign in with no password to phish or steal.

Every token is RS256-signed with a dedicated RSA-2048 key per application.

Private keys are encrypted at rest. Signed Connect /establish requests use replay protection.

Passkeys, email OTP, Steam, and OAuth providers — gated per application.

## Privacy by design

Each application receives a per-user pairwise identifier, never your underlying account.

Choose per application whether it can receive your email and name through UserInfo.

Erase your account and personal data. If you solely own an organization with live applications or sectors, retire those resources or add another active owner first.
