Dear PG administrators

I am going to conduct some trailhead activities.
Recentrly, I had MFA activities on my PG, then logout.
However, I cannot connect/run on my PG based due to forgot my login id/passwd combination for my PG.
I also try to reset passwd, but I forgot QA's combination.

Could someone help/reset my passwd to enter into my PG.

PG URL:https://empathetic-fox-qhrzqt-dev-ed.my.salesforce.com/

If needs, I also provide more information.

With best regards,

// Jun
