Well there is a listener for auth events...
which wont be uper helpful in that case I guess...

maybe this will shed light on that?

But you will need to execute that for the user that is logged in. You need to use the admin API it seems.
ChatGPT was answering this which sounds reasonable:
To log out a user from Supabase as an admin, you'll generally have two main options:

### 1. Revoke the User’s Session (via API)

You can revoke a user's session using Supabase's Admin API. This essentially invalidates the user's access token, which logs them out. Here’s how to do it:

- Step 1: Get the user's current session ID (if tracking sessions).

- Step 2: Use the Admin API to revoke the session, invalidating their access.

Here's an example of how you might do this in JavaScript:

```javascript

import { createClient } from '@supabase/supabase-js'

// Initialize Supabase with the Admin key

const supabaseAdmin = createClient('https://your-project-ref.supabase.co', 'your-supabase-admin-key')

// Function to log out a user by revoking their token

async function revokeUserSession(userId) {

const { error } = await supabaseAdmin.auth.admin.signOut(userId)

if (error) {

console.error('Error logging out user:', error.message)

} else {

console.log('User has been logged out')

}

```

In this example:

- Replace https://your-project-ref.supabase.co with your Supabase project URL.

- Replace 'your-supabase-admin-key' with your Supabase Admin API key.

- Call revokeUserSession() and pass the specific userId you want to log out.

### 2. Delete the Refresh Token

If you want to log out all sessions for the user, deleting their refresh token can help. This removes any active sessions and prevents the user from refreshing expired access tokens.

```javascript

// Use the Supabase Admin client to delete the refresh token

async function deleteUserRefreshTokens(userId) {

const { data, error } = await supabaseAdmin.auth.admin.deleteRefreshTokens(userId)

if (error) {

console.error('Error deleting refresh tokens:', error.message)

} else {

console.log('All refresh tokens deleted for user')

}

```

Deleting refresh tokens is a more permanent approach, ensuring the user will have to reauthenticate fully before they can log in again.

### Notes

- Supabase Admin Key Security: Ensure your Admin API key is kept secure as it provides elevated access.

- Limited Session Control: Supabase currently doesn’t offer complete session management like a dedicated logout function across all active sessions, so deleting tokens is the most direct way to handle it.

Let me know if you need help with implementing this in a specific language or framework!
