License Authentication (OAuth)

SentinelSecurity authenticates your license through an OAuth connection with your Sentinel Suite account. No manual license key entry is required.

Authentication Steps

Go to SentinelSecurity → License
Click the Connect to Sentinel Suite button
The Sentinel Suite login page will open in a new tab
Log in with your Sentinel Suite account
Click Authorize this site to approve the connection
You will be automatically redirected back to the WordPress admin panel, and authentication is complete

After Authentication

Once authentication is successful, the License Management screen will display:

License Status: Active / Expired / Not authenticated
Plan Name: Your purchased plan
Expiration Date: Next subscription renewal date
Authorized Domain: The domain linked to the license

Subscription Management

Renewal

Subscriptions are renewed automatically. Manage your credit card information in the My Page section of your Sentinel Suite account.

Changing Plans

Log in to My Page on Sentinel Suite
Open Subscription Management
Change or update your plan

Cancellation

Even after canceling your subscription, features remain available until the end of your current billing period. After expiration, license-protected features become restricted.

Transferring a License

If you change your site's domain or want to use the license on a different site, you need to transfer the license (deactivate → reactivate).

Steps

On the old site, go to License Management → click Deactivate
On the new site, re-authenticate via Connect to Sentinel Suite

Automatic Restoration

If you temporarily deactivate the plugin and then reactivate it, your license information will be automatically restored. No re-authentication is required.
