Personal shop password

how do I get to personal shop? I never set a password and it tells me it’s incorrect? Wtf?

It is likely asking you to set it up. The password you create must be a series of 5 numbers, no letters, no symbols.

If you really do need to reset it, go to the support site, click "Submit a request" in the top right corner, and then select "Item Shop Password Reset (2nd Password)".
