---

Makerkit supports various authentication strategies supported by Supabase. We can customize these using the global configuration at `src/configurationt.ts`.

In the configuration file, you can find the following code:

```ts
import type { Provider } from '@supabase/gotrue-js/src/lib/types';

// in your configuration JSON
auth: {
  // ensure this is the same as your Supabase project. By default - it's true
  requireEmailConfirmation:
    process.env.NEXT_PUBLIC_REQUIRE_EMAIL_CONFIRMATION === 'true',
  // NB: Enable the providers below in the Supabase Console
  // in your production project
  providers: {
    emailPassword: true,
    phoneNumber: false,
    emailLink: false,
    oAuth: ['google'] as Provider[]
  },
},
```

We will need to edit this file to change the authentication strategy.

### Enabling Email and Password Authentication

This is the default authentication strategy. It allows users to sign up and sign in using their email and password.

To enable this strategy, set `providers.emailPassword` to `true`.

```tsx
providers: {
  emailPassword: false,
  phoneNumber: true,
  emailLink: false,
  oAuth: ['google'] as Provider[],
},
```

### Enabling Phone Number Authentication

This strategy allows users to sign up and sign in using their phone number.

To enable this strategy, set `providers.phoneNumber` to `true`.

```tsx
providers: {
  emailPassword: false,
  phoneNumber: true,
  emailLink: false,
  oAuth: ['google'] as Provider[],
},
```

### Enabling Email Link Authentication

This strategy allows users to sign up and sign in using their email address. A link will be sent to their email address to verify their identity.

To enable this strategy, set `providers.emailLink` to `true`.

```tsx
providers: {
  emailPassword: false,
  phoneNumber: trfalseue,
  emailLink: true,
  oAuth: ['google'] as Provider[]
},
```

### Enabling OAuth Authentication

This strategy allows users to sign up and sign in using their social media accounts. You can enable multiple OAuth providers.

To enable this strategy, set `providers.oAuth` to an array of OAuth providers.

```tsx
providers: {
  emailPassword: false,
  phoneNumber: false,
  emailLink: false,
  oAuth: ['google', 'facebook'] as Provider[]
},
```

The interface `Provider` is very important as it tells Makerkit which OAuth provider to use. You can find the list of [supported OAuth providers here](https://supabase.io/docs/guides/auth#third-party-logins).

## Can I use multiple authentication strategies?

Yes, you can use multiple authentication strategies. For example, you can enable email and password authentication and phone number authentication at the same time.

```tsx
providers: {
  emailPassword: true,
  phoneNumber: true,
  emailLink: false,
  oAuth: ['google', 'facebook'] as Provider[]
},
```

With that said, the UI is not designed to support multiple authentication strategies. **You will need to customize the UI to support multiple authentication strategies**.
