Welcome to Atlassian Community!
Checking the details of your site, I can see that there are three demo accounts and none of them are redirected to login with SSO, the same as your account.
I'm not sure if that's what you meant. If it's not, can you please let us know more details about "user password not synchronized"?
Did you follow all the steps mentioned in the documentation below?
The domains are correctly verified on your organization, but it seems that you are not using SAML.
If there are any errors on the UI, feel free to share with us a screenshot (just make sure to hide private information).
