# Email Verification: Advanced Settings Reference

## Advanced settings reference

The Advanced sub-tab of [Customer Email Verification for WooCommerce](https://wpfactory.com/item/email-verification-for-woocommerce/) holds the low-level options you reach for when the default verification flow needs tuning: which authentication filter to hook, how activation codes are encoded, and when a user is logged out after registering or checking out. This reference lists every option on that sub-tab with its option id and default, verified against version 3.2.7.

### Where to find it

Go to **WPFactory > Email Verification** (also reachable at **WooCommerce > Settings > Email Verification**) and open the **Advanced** sub-tab.

### Advanced options

| Label | Option ID | Default |
| --- | --- | --- |
| Authenticate filter | `alg_wc_ev_auth_filter` | `wp_authenticate_user` |
| Block auth cookies | `alg_wc_ev_block_auth_cookies` | No |
| Custom "logout" function | `alg_wc_ev_custom_logout_function` | No |
| Replace HTML tags | `alg_wc_ev_replace_html_tags` | No |

The **Authenticate filter** chooses which WordPress hook the plugin uses to reject unverified logins: `wp_authenticate_user`, `authenticate`, or `send_auth_cookies`. Switch to `authenticate` to make the verification error take priority over the incorrect-password error. **Block auth cookies** is the option to enable if unverified users are still able to log in.

### Encoding options

| Label | Option ID | Default |
| --- | --- | --- |
| Encoding method | `alg_wc_ev_encoding_method` | `base64_encode` |
| Hashids salt | `alg_wc_ev_hashids_salt` | Auto-generated |
| Hashids alphabet | `alg_wc_ev_hashids_alphabet` | `abcdefghijklmnopqrstuvwxyz1234567890` |

The encoding method controls how the activation code inside the verification link is built. If you switch to **Hashids**, set an unpredictable random value in the salt field: leaving it empty is flagged in red because it weakens the code.

### Prevent login after register

| Label | Option ID | Default |
| --- | --- | --- |
| Prevent login after register | `alg_wc_ev_prevent_login_after_register` | Yes |
| Login prevention method | `alg_wc_ev_prevent_login_after_register_method` | `logout_after_login` |
| Redirect | `alg_wc_ev_prevent_login_after_register_redirect` | No redirect |
| Custom redirect URL | `alg_wc_ev_prevent_login_after_register_redirect_url` | Empty |
| Force redirect | `alg_wc_ev_prevent_login_after_register_session_redirect` | No |

### Prevent login after checkout

| Label | Option ID | Default | Free/Pro |
| --- | --- | --- | --- |
| Prevent login after checkout | `alg_wc_ev_prevent_login_after_checkout` | Yes | Free |
| Prevent login action | `alg_wc_ev_prevent_login_after_checkout_action` | `woocommerce_get_return_url` | Free |
| Prevent login notice | `alg_wc_ev_prevent_login_after_checkout_notice` | Yes | Free |
| Block thank you page | `alg_wc_ev_prevent_login_after_checkout_block_thankyou` | No | Pro |

### Background processing

| Label | Option ID | Default |
| --- | --- | --- |
| Minimum amount | `alg_wc_ev_bkg_process_min_amount` | 20 |
| Send email | `alg_wc_ev_bkg_process_send_email` | Yes |
| Email to | `alg_wc_ev_bkg_process_email_to` | Site admin email |

Bulk actions such as verifying, unverifying or deleting many users run in the background once the result count passes the **Minimum amount** threshold, so the admin screen stays responsive.

### REST API and delete options

The Advanced sub-tab also holds the **Verify endpoint** option (`alg_wc_ev_rest_api_verify_endpoint`, a Pro feature) and the tools for deleting unverified users. Those are covered in their own articles: see the guides on verifying users through the REST API and on deleting unverified users.

### Get the full toolkit
