NO! Please do not EVER give out that information. Any Shopify Partner or Expert will request access to your store via collaborator access. This is a standard in the Shopify world and anyone who requests this or a staff account is either a bad actor or not familiar enough with Shopify. When collaborator access is requested, you sign off on specific permissions so I'm not able to access parts of your store that I do not need.Here's a link to Shopify's docs on that.
