Email & password

EmailPasswordPlugin enables password signup and sign-in. Session, password-reset, and account-management modules are already included by the builder.

Setup

Use the generated schema and store from installation:

use crate::auth_schema::AppAuthSchema;
use better_auth::plugins::EmailPasswordPlugin;
use better_auth::sqlx::SqlxStore;
use better_auth::{AuthConfig, AuthResult, BetterAuth};

async fn build_auth(
    config: AuthConfig,
    store: SqlxStore<AppAuthSchema>,
) -> AuthResult<BetterAuth<AppAuthSchema>> {
    BetterAuth::<AppAuthSchema>::new(config)
        .store(store)
        .plugin(
            EmailPasswordPlugin::new()
                .enable_signup(true)
                .password_min_length(12),
        )
        .build()
        .await
}

Signup uses /sign-up/email; sign-in uses /sign-in/email. See basic usage for requests.

Options

Use auto_sign_in(false) to require sign-in after signup, or require email verification before issuing sessions. Username sign-in is configured on the same plugin.

The default hasher is ScryptHasher. Supply a PasswordHasher through password_hasher when using an existing credential format. Password-reset delivery is configured through PasswordManagementPlugin.
