Auth0 and Firebase both offer robust user authentication solutions but cater to slightly different needs. Auth0 is known for its flexibility and ease of integration, making it a good choice for organizations looking for a customizable solution without the hassle of building from scratch. Firebase, on the other hand, is part of Google's larger app development platform and offers a generous free tier along with a low cost per monthly active user. It also supports a wide range of authentication methods, including email/password, phone, magic links, two-factor authentication, and multiple social identity providers. If cost efficiency and a wider range of authentication methods are your priorities, Firebase may be the better choice. However, if you need a highly flexible and customizable solution, Auth0 might be more suitable.

Firebase tends to be more cost-effective for scaling user authentication. Firebase's pricing starts at $0.0055 per monthly active user (MAU) and can go as low as $0.0025 per MAU as you scale to millions of users. Additionally, Firebase offers a generous free tier that includes 50,000 MAUs. Auth0 does not have detailed pricing information readily available, which suggests that costs may vary based on specific requirements and usage patterns. Therefore, if cost is a critical factor, especially as you scale, Firebase might be the more economical choice.
