Better Auth RS

Database

AuthSchema selects the application’s user, session, account, and verification models. Your application owns the models and migrations.

Generate a schema

Section titled “Generate a schema”
Terminal window
better-auth-rs generate -o src/auth_schema.rs

The output contains all four models, AppAuthSchema, and SQLx migration scaffolding. Include it with mod auth_schema; as shown in installation.

Role Stores
User Identity and profile
Session Credential, expiry, and ownership
Account Password or provider credentials
Verification Time-limited proofs

Add plugin fields

Section titled “Add plugin fields”
Terminal window
better-auth-rs generate --plugins username,admin,two-factor -o src/auth_schema.rs

Review generated changes before replacing an existing schema. New Rust fields still need database migrations.

run_app_migrations bootstraps a new SQLx database. SchemaMigrator::migrate installs the bundled schema and its ledger; it does not migrate arbitrary application models. Keep your own versioned migration system as the schema evolves.

Continue with SQLx, SeaORM, or existing databases. Additional fields control API input and output separately from physical models.
