Log-out all users with Laravel and Redis

Last week we had a need to force users to log out of our Laravel app. Depending on the session driver you use this can range from trivial to difficult. In this instance we were using Redis as our session driver.

You cannot just reset your Redis instance - users will be able to refresh their session using their remember_token cookie. So first, clear the remember_token for the affected users.

User::whereIn('id', [...])->each(function (User $user) {
    $user->forceFill([
        'remember_token' => null,
    ])->save();
});

Next, flush the Redis database. This will clear all sessions, however it should not affect users who still have a valid remember_token as they will remain logged in.

Illuminate\Support\Facades\Redis::connection('default')->flushdb();
