SolidJS Authentication: What Framework Should You Use?

SolidJS is a popular choice among frontend developers seeking React-like reactivity without the overhead, and is increasingly used for full-stack development with SolidStart. However, authentication remains a challenge, as common approaches like storing JWTs in localStorage can be insecure and unreliable at scale. Developers often choose between manual JWT setups, managed services like Firebase or Auth0, or open-source frameworks such as SuperTokens, which offers a more secure and flexible solution. SuperTokens provides SolidJS developers with tools for secure authentication, integrating seamlessly with Node.js backends and offering features like email-password, passwordless, and third-party logins. While managed services can lead to vendor lock-in and rising costs, SuperTokens offers an open-source alternative that balances security and flexibility without sacrificing control, making it a compelling choice for SolidJS projects needing scalable authentication solutions.
