Any updates on this? Better Auth hit v1 a few months ago (on Nov 2023) and is such a good auth solution. Clears NextAuth/Auth.js imo and does everything better. Here are some things I can think of off the top of my head:

• Significantly better docs than NextAuth/Auth.js (Better Auth docs cover almost every edge case, unlike Auth.js v5 beta where I had to look up 3rd party guides to setup slightly more 'complex' features)
• Does all the basics
  • Email/password (this is not a 2nd class option on Better Auth)
  • Credentials-based auth with either email, username, or phone numbers
  • Magic Links
  • OTP (for both email and phone numbers)
  • OAuth
  • 2FA
  • Passkeys
• Lotta "advanced" stuff (built-in rate limiter, better RBAC, organizations, anonymous users, SSO and more)
• Supports Expo too (for create-t3-turbo users)
• Migration guide for existing NextAuth/Auth.js users here (can be included in the T3 docs for existing Auth.js users)

I'm only glazing on Better Auth this much because it'd be a good fit for create-t3-app cus it's also:

• OSS and self-hosted auth (just like Auth.js, unlike Clerk)
• Not a managed auth provider, that happens to let you self-host it (like Supabase Auth, SuperTokens, or Stack Auth)
• Not a low-level "roll-your-own-auth-on-your-own" solution like Lucia or iron-session (mentioned it since the maintainers didn't want to add Lucia to create-t3-app)

Would love to see this added in! If this is something the maintainers would be open to, I'd love to work on the PR to get this added in!
