Auth0 by Okta provides a comprehensive suite of features including social login, bot detection, UI components, anonymous users, single-sign-on, and multi-factor authentication (MFA). It also supports a free tier with 7,500 monthly active users (MAUs). However, it can be relatively expensive, with costs reaching $1400/month for 20,000 MAUs. On the other hand, GoPasswordless focuses on enabling passwordless authentication flows in web apps. If you need a broad range of features and can manage the cost, Auth0 by Okta might be the better choice. If your primary concern is implementing passwordless authentication, GoPasswordless could be a more targeted and potentially cost-effective solution.

Auth0 by Okta offers a free tier that supports up to 7,500 monthly active users (MAUs) but can become relatively expensive, costing up to $1400/month for 20,000 MAUs.
