Cakephp 3: Shared Database Session Across Multiple Apps

I have two Cakephp 3 apps that save their sessions on the same “sessions” table on the same database. I’ve been trying to set it up so that they share the same sessions, so that when I’m logged in to either one, I’m automatically logged in to the other.

I have this in both of their app.php files:

'Session' => [
    'defaults' => 'database'

And this is the “sessions” table they’re both using:

Logging into both results in them having different entries in the table.

Thanks in advance for any suggestions.
