How to remove the session ID from the URL in Magento 2 (frontend). This is the SID query parameter in the URL.

For example: https://example.com/contact/?SID=sfl317buq8ru4uf4a...

Removed starting from 2.3.3 https://github.com/magento/magento2/issues/25663


Go to the Store > Configuration > General > Web > Session Validation Settings > Use SID on Storefront and set its value to No


Here is the good answer about the SID:

The SID is a "session ID". Magento uses this to track a user's activity within the same Magento installation. Normally, Magento powers one website and one store from one installation (database).

Magento could power multiple websites with multiple stores from one installation though. The SID allows users to stay logged in while navigating across these websites/stores.

I think if you have the function enabled, the SID is sent when accessing catalog URLs so Magento can update the session with the user's location/state for the current website/store.

If you're not running a multi-website or multi-store environment, it's safe to disable the SID on the frontend.

    I've used this approach and disabled SID on the front-end, also Single-store mode set to "Yes", the SID still shows up. In production mode, should we regeneration files to make this work? I don't think so since it's a config value. Any ideas? – dchayka Jan 13 '17 at 20:48
  • @dchayka I think this might be a cache issue. Try to refresh it. – Siarhey Uchukhlebau Jan 16 '17 at 6:13
  • @SiarheyUchukhlebau cache has been refreshed. I figured out what it is. Thank you for following up. – dchayka Jan 16 '17 at 14:12
  • @SiarheyUchukhlebau How Can I change the meta tag for example.com/?SID=nufp7tmaardcoff2ddbp4vmmo6 in magento 2?? – supriya mishra Jan 27 '17 at 6:59

Those of you who already set Use SID on Storefront to No (as Siarhey Uchukhlebau pointed out in his answer) but still can't get rid of &sid=... in the URL, check out following links.

It is a Magento Bug, which will be fixed in version 2.3
Related ticket: https://github.com/magento/magento2/issues/9453

Fortunately, there is a Inchoo Tutorial on how to remove it via .htaccess file as workaround

  • Magento 2.3 is released. Has this been fixed? Can't find anything about it. – Akif Dec 24 '18 at 13:24
  • I'm not using Magento 2.3, but in Magento 2.2.6 I'm not facing this issue anymore. – MichiP Jan 24 '19 at 10:29

Isn't ?SID automatically added by PHP if PHP is configured to not store sessions on the server or the browser doesn't accept cookies?

I believe Magento doesn't do this by default. There is a setting for it, but I'm assuming that the OP didn't change this, otherwise he would have figured this out by himself.

    If the PHP run-time option session.use_trans_sid is enabled, relative URIs will be changed to contain the session id automatically. This option is not on by default. Magento 2's default setting for "Use SID on Storefront" is "Yes". – t-richards Jan 15 '18 at 21:48

Use Frontend SID removed from store configuration settings from a Magento update. However the value may still be set to 1 in the core_config_data table.

Update your MySQL database table 'core_config_data' and set the value to '0' for path 'web/session/use_frontend_sid'. Do this for all store values.

UPDATE core_config_data SET value = '0' WHERE path = 'web/session/use_frontend_sid';

Find the function and comment the line as below.

public function getUseSessionInUrl()
   // return $this->_useSessionInUrl;

    Don't edt Magento core files. Also after the next Composer command, the contents of vendor/magento/framework/ might get restored/updated – 7ochem May 14 '18 at 12:16
