@RishitKedia both @luceos and I have reviewed the SSO extension you requested.
We are not comfortable with installing this particular extension as it would have
a) a negative performance impact and
b) cause unwanted side effects in terms of security
I realise this is not quite the answer you were looking for, but we must only allow code into our stack that we are confident will not impact your site, or the sites of other clients.
I'm happy to work with you to explore if any other extensions might be sufficient for your needs.
