Describe the solution you'd like

It's a popular flow to first enter your email, click continue and then see a different page depending if the email exists in the system. would be great to have an api to check email and see if it exists or not to support this popular flow.

Describe alternatives you've considered

checking database directly.

we throw an error for you with proper error message for that

{"code":"USER_ALREADY_EXISTS","message":"User already exists"}

you can this to be able to do your flow. it is also easier and convenient to do in one round trip as well.

@Kinfe123 When is such error thrown? when we call signup? you suggest that I create a random password and call to signup a user? and then delete the user since he hasn't agreed to sign up yet. It's very clean if a user already exists, but if user doesn't, it's very hacky and goes against policy - since creating accounts requires users accepting terms and conditions. Or at least, can we make passwords optional - that will make this case less hacky and partially solve https://github.com/better-auth/better-auth/issues/4396
