Question: I'm looking for a way to improve user conversion rates while maintaining strong security measures for authentication.

It supports multifactor authentication, advanced security controls and multiple login options like social sign-on and one-time passcodes. Clerk integrates with common frameworks and tools and has multi-tenancy support, too, so it's a good option for secure and efficient user management.

Another option is MojoAuth, a passwordless authentication service that's designed to avoid the security problems of passwords. It's designed to provide a frictionless login experience, better security and higher user satisfaction.
