Reasons buyers look elsewhere
- Certain tools focus on specific authentication technologies such as passwordless login, passkeys, or biometric authentication. Developers who want these specialized capabilities may prefer platforms built specifically around those authentication models.
- Some authentication platforms offer larger ecosystems with deeper integrations across enterprise software, identity providers, and compliance tools. Organizations with complex system architectures may choose platforms designed to support large enterprise environments.
- Certain development teams prefer authentication platforms that allow self-hosting or full control over user data and infrastructure. Open-source solutions or self-managed authentication systems provide more flexibility and avoid dependence on a third-party service.
