Better Auth

Better Auth is such a great project.
Use it alot, thank you guys

Wow that was a lot. Looks like you’ve been busy lol
Great new additions to the project.

I loved better-auth until I had to use it with Capacitor. Now I’m running into one issue with buggy plugins after another, and a system that is near impossible to debug once deployed ☠️⚰️!
