Wristband

Wristband is a platform designed to help SaaS applications implement authentication flows tailored for multi-tenant architectures. It addresses the challenges of managing user authentication and tenant isolation by providing hosted login pages, APIs, and SDKs that streamline the integration process for developers building multi-tenant apps.

The tool offers a comprehensive set of features for managing authentication and user identity. Developers can use Wristband’s SDKs to redirect users to hosted login pages, which can be customized for each tenant, including support for vanity domains and tenant discovery. After authentication, Wristband handles callback requests and provides authorization codes that can be exchanged for tokens, enabling secure session management. The platform supports verification of authenticated states both on the frontend, by managing session cookies, and on the backend, by validating access tokens with public signing keys and supporting token refresh workflows.

Wristband’s APIs allow for robust user and tenant management within applications. Features include updating user profiles, changing passwords, securely managing email changes, and enrolling users in multi-factor authentication (MFA). Tenant administrators can use the APIs to invite new users, configure identity providers for single sign-on (SSO), and set security policies such as MFA at the tenant level. The platform emphasizes strict tenant isolation, ensuring that users belong to a single tenant and that user data is logically separated to prevent cross-tenant conflicts. Tenants have full ownership of their users, and the system supports simultaneous logins to multiple tenants.

Customization is a key aspect, with options to fully brand authentication pages and emails, adjust login methods, and configure security policies for each tenant through the dashboard or APIs. Wristband also supports common user workflows out of the box, such as user invitations, self-signup, email verification, and secure email changes. NET. The platform is positioned as a solution for SaaS developers seeking to implement secure, customizable, and isolated authentication flows for multi-tenant environments.
