My magento store was created by 3rd party company, and then they didn't set up our email address for our account, now our account is locked some reason, we could not login in, how could we do?
Hi @sara5201988
Do you mean you are not able to login to admin?
If you have access to code on the server you can create a new admin user with your email id.
Please refer for Magento1 https://magento.stackexchange.com/a/161022
For Magento2 https://www.mgt-commerce.com/tutorial/how-to-create-a-new-magento2-administrator-account and https://magento.stackexchange.com/a/176573
If you don't have a working password for your Magento admin and don't have the option to reset the password via traditional means, you may need to address this directly via your Magento database.
What version of Magento are you using?
