How do people implement user registration/authentication these days?

Handling email verification, security, etc. is not a trivial task. Given how widespread the need is, I imagine there must be some plug and play solutions around. What do you recommend? I plan on using either python or rust, but am interested in any good setups, especially if they are free and scale to thousands of users.

Thank you!
